 ELIZABETH -- An improvised explosive device in a backpack detonated near the Elizabeth train station early Monday as authorities were using a bomb robot to examine the item, officials said. 
 
 The blast occurred around 12:40 a.m. near Morris Avenue and Julian Place. The explosion was not a controlled blast, but happened unintentionally as the robot was cutting the device, according to Mayor Christian Bollwage. No one was injured in the blast, Bollwage said. 
 
 Authorities found five devices inside a single backpack near the train station, including one that was detonated. After the explosion, press and bystanders were moved back because the four other explosive devices inside of the backpack were still believed to be live, Bollwage said. 
 
 No other explosions were heard as of 5 a.m. 
 
 
 
 
 
 On Twitter, the FBI's Newark division described the devices as "multiple improvised explosive devices." 
 
 Earlier Sunday night, the FBI detained five people in Brooklyn for questioning related to the Saturday night explosion in Manhattan that injured more than two dozen people. 
 
 The Elizabeth incident unfolded after two men found the backpack in a waste basket on North Broad Street and Julian Place around 8 p.m. Sunday, the mayor said. 
 
 The men took the backpack "because they thought it was of some value," walked for a bit, then saw wires and a pipe, dropped the package and notified Elizabeth police, he said. 
 
 Bollwage told reporters the explosives were originally found in the trash can about 300 feet from the door of Willy's Place near the train station in the city of about 125,000, which is also the Union County seat. 
 
 "If that pub was crowded and there was a lot of people there, it could have severely injured, killed and maimed many, many people," Bollwage told reporters. 
 
 Bollwage said the Elizabeth devices did not contain a cell phone or any other electronic detonators. 
 
 After the items were found, Union County's Bomb Squad was called in and used a drone to examine the backpack, the mayor said. 
 
 "The drone indicated it could be suspicious and it could be a live bomb," Bollwage said. 
 
 When asked if he ever thought Elizabeth would be the target of such an attack, Bollwage said he was not sure the city was the intended target and that the devices could have instead been dumped by a person who realized he or she was being investigated. 
 
 "I'm not willing to admit Elizabeth is a terror target," Bollwage said. "Because of the location, it's very possible someone was trying to get rid of package as opposed to set it off." 
 
 Bollwage said FBI agents are reviewing surveillance footage from the restaurant near the trash can where the backpack was first found by the two men. 
 
 
 
 
 
 Reached after midnight on Monday morning, a spokesman for the FBI in Newark, Special Agent Michael Whitaker, said only that his agency had responded to the scene, and declined to provide any details of the investigation. 
 
 The FBI asked anyone with information to call 1-800-CALL-FBI. 
 
 Police cordoned off the station and many streets surrounding it. The investigation halted train service on the busy Northeast Corridor and North Jersey Coastline commuter rail lines. Later, officials said service would resume at 5:30 Monday, with delays expected. 
 
 Tickets and passes on both rail lines are being cross-honored on PATH along with NJ Transit and private buses, according to the transit agency. 
 
 Amtrak service was also suspended near Elizabeth, spokesman Craig Schulz said in a statement. 
 
 "We apologize to our customers for the inconvenience and will resume service as soon as it is safe to do so," the spokesman said. 
 
 Approximately 2,400 Amtrak passengers were impacted by the service suspension, the spokesman said. 
 
 "Robust security measures are in place at stations, on trains and along the tracks and Amtrak Police remain in close contact with local, state and federal partner agencies to coordinate and share intelligence information," the statement said. "At this time there are no specific or credible threats against Amtrak." 
 
 It was not immediately clear if the Elizabeth incident was linked to a bombing Saturday night in New York City that injured 29 people or another pipe-bomb style device that went off near a military charity race in Seaside Park also on Saturday.

(AP) — A suspicious device found in a trash can near a New Jersey train station exploded early Monday as a bomb squad was attempting to disarm it with a robot, officials said. 
 
 Elizabeth Mayor Christian Bollwage said that the FBI was working to disarm one of five devices found in the same bag, which was discovered in a trash can by two men around 8:30 p.m. Sunday, near the Elizabeth train station on New Jersey Transit's Northeast Corridor rail line. The men had reported seeing wires and a pipe coming out of the package, Bollwage said. 
 
 There was no immediate report of injuries or damage. A message left with the FBI wasn't immediately returned. The mayor warned that other explosions were expected. 
 
 NJ Transit service was suspended early Monday between Newark Liberty Airport and Elizabeth, and New Jersey-bound Amtrak trains were being held at New York Penn Station, officials said, while New York-bound Amtrak trains were being held in Trenton. 
 
 Train passengers reported being stuck on Amtrak and NJ Transit trains for hours Sunday night, while some trains moved in reverse to let passengers off at other stations. Amtrak said 2,400 passengers were affected and that trains were being brought into other stations for people to get other transportation. It wasn't clear when the Elizabeth station would be open, a threat to cause major issues on the Monday morning commute into New York. 
 
 The discovery of the suspicious package comes a day after an explosion in Manhattan injured 29 people, and an unexploded pressure-cooker device was found four blocks away. Also Saturday, a pipe bomb exploded about an hour from the Elizabeth train station in Seaside Park, New Jersey, forcing the cancellation of a military charity 5K run. Officials said it didn't appear that those two incidents were connected, though they weren't ruling anything out. 
 
 Investigators didn't immediately comment on whether they thought the Elizabeth incident was connected to either of the two blasts. 
 
 Bollwage said that he wasn't willing to say that Elizabeth had become a target, and that it was possible that someone worried about the authorities was trying to get rid of the package. 
 
 "I'm extremely concerned for the residents of the community, but more importantly extremely concerned for everyone in the state and country where someone can just go and drop a backpack into a garbage can that has multiple explosives in it with no timers and then you have to wonder how many people could have been hurt," Bollwage said.

 This story has been corrected to show that the bag was found around 8:30 p.m., not 9:30 p.m. ||||| New York (CNN) The man suspected in Saturday's bombings in New York and New Jersey was captured on Monday after a frantic manhunt and shootout. 
 
 Authorities said Rahami is "directly linked" to bombings Saturday in New York City and Seaside Park, New Jersey , and is believed to be connected to pipe bombs found Sunday night in Elizabeth, New Jersey, sources said. 
 
 "We have every reason to believe this was an act of terror," New York Mayor Bill de Blasio said Monday. 
 
 But many questions remain, chief among them, why did he do it? And, is anyone else responsible? 
 
 Ahmad Khan Rahami was wounded in a shootout with police in Linden, New Jersey. 
 
 The arrest 
 
 Rahami was captured after the owner of a bar in Linden, New Jersey, found him sleeping in the doorway of his bar Monday morning. Harinder Bains, owner of Merdie's Tavern, said he was watching CNN on his laptop from another business across the street. At first, he thought he was some "drunk guy" resting in the vestibule. Then, he recognized Rahami and called police. 
 
 "I'm just a regular citizen doing what every citizen should do. Cops are the real heroes, law enforcement are the real heroes," Bains told CNN's Anderson Cooper. 
 
 When officers responded, Rahami pulled out a handgun and opened fire, striking an officer in the chest. A foot chase ensued, during which Rahami shot at a police car, causing a bullet to graze another office in the face. 
 
 The chase ended when Rahami was shot multiple times. He was taken to a hospital for surgery. Officers Angel Padilla and Peter Hammer were taken to the hospital for treatment of non-life threatening injuries.

 Rahami was not initially cooperative with police who tried to interview him, a law enforcement official said. 
 
 Authorities believe the "main guy" has been caught but the investigation continues to determine if Rahami had help, sources told CNN. 
 
 Though FBI Assistant Director William F. Sweeney Jr., said there is "no indication" of an active operating cell in the New York area, evidence suggests Rahami was not acting alone, sources told CNN. 
 
 As the investigation continues, law enforcement has stressed there is no reason to believe a bomber is on the run. 
 
 The investigation 
 
 Initially, a garbage explosion at a Marine Corps charity race in Seaside Park, New Jersey, seemed to be an isolated incident. Two other unexploded bombs were found nearby and no one was wounded in the blast.

 Then came another blast Saturday night in New York's Chelsea neighborhood, injuring 29 people. As law enforcement cordoned off the area, investigators found a pressure cooker four blocks away. 
 
 Dark-colored wiring was connected by silver duct tape to what appeared to be a cell phone. Ball bearings and BBs were among pieces of metal that appeared to be packed inside, a federal law enforcement official said. A handwritten note found next to it contained ramblings, including references to previous terrorists, including the Boston Marathon bombers.

 Surveillance video shows a man believed to be Rahami dragging what appears to be a duffel bag with wheels near the site of the West 23rd Street explosion about 40 minutes before the blast, according to multiple local and federal law enforcement sources. 
 
 About 10 minutes later, surveillance video shows the same man with the same duffel bag on West 27th Street, multiple law enforcement sources said. 
 
 A device at a second location in Chelsea appears to be a pressure cooker. 
 
 In the video, the man leaves the duffel bag where police later found the unexploded pressure cooker. After he leaves, the video shows two other men removing a white garbage bag believed to contain the pressure cooker from the duffel bag and leaving it on the sidewalk, according to a senior law enforcement official and another source familiar with the video. 
 
 Investigators have not determined if those two men are connected to the man with the duffel bag, the sources said. 
 
 Rahami was identified Sunday afternoon through a fingerprint, a senior law enforcement official said. Evidence from the cell phone on the pressure cooker also led to Rahmani's identification. 
 
 A traffic stop Sunday night of five people in New York led to searches and interviews in Elizabeth, New Jersey, said Sweeney with the FBI. Rahami's last known address was in Elizabeth, the same city where the backpack with explosives was found Sunday night. 
 
 The latest bomb discovery 
 
 The backpack with five bombs inside was found in a wastebasket around 9:30 p.m. on Sunday outside a neighborhood pub in Elizabeth, about 16 miles from New York City. Two men found the backpack about 500 feet from a train trestle and alerted police, officials said.

 As bomb technicians deployed a robot to examine the devices, one of the bombs detonated. The remaining four were taken to an FBI laboratory at Quantico, Virginia, Elizabeth Mayor J. Christian Bollwage said. 
 
 Police checked all garbage cans in the immediate area but found no other suspicious items. 
 
 By Monday, authorities said they believed Rahami was linked to the explosion. 
 
 CNN Map 
 
 Who is the suspect? 
 
 Rahami first came to the United States in 1995 as a child, after his father arrived seeking asylum, and became a naturalized US citizen in 2011, according to a law enforcement official who reviewed his travel and immigration record. 
 
 Rahami traveled for extended periods to Afghanistan and Pakistan in the last five years, officials said. While in Pakistan in July 2011, he married a Pakistani woman. Two years later, in April 2013, he went to Pakistan and remained there until March 2014, visiting Afghanistan before returning to the United States. 
 
 Upon returning from both visits he told officials he was visiting family, satisfying any concerns immigration officials had at the time. 
 
 His family runs First American Fried Chicken in Elizabeth, the city's mayor said. The family has a history of clashes with the community over the restaurant, which used to be open 24 hours a day, Mayor Chris Bollwage said. 
 
 In 2011, the family sued the city of Elizabeth, and its police department, alleging discrimination and harassment against Muslims stemming from disputes over the restaurant's hours. Investigators searched the building on Monday, Bollwage said. 
 
 'Bigger than ever' NYPD presence 
 
 The bombings came as New York hosts world leaders at the United Nations General Assembly this week. 
 
 Heightened security across the city is common during the UNGA. But after the Chelsea bombing, Cuomo said 1,000 additional New York State Police officers and National Guard troops will be deployed to patrol bus terminals, airports and subway stations. 
 
 "You should know you will see a very substantial NYPD presence this week -- bigger than ever," de Blasio said. 
 
 Substantial police presence notwithstanding, life appears to have returned to normal, whether you call it resilience or resignation. 
 
 As President Obama said Monday, "we all have a role to play as citizens" by making sure we don't succumb to fear. 
 
 People in the region are tough and resilient, he said. 
 
 "They don't get scared," he said. "That's the kind of strength that makes me so proud to be an American. And, that's the kind of strength that is going to be absolutely critical, not just in the days to come, but in the years to come." ||||| ELIZABETH, N.J.

 MANHATTAN — An explosion rocked Chelsea Saturday night, injuring 29 people on West 23rd Street and Sixth Avenue. A second bomb was found four blocks away at West 27th Street, but it did not go off. Authorities have since connected those bombs with others found in New Jersey. 
 
 Here's what we know and what questions remain unanswered: 
 
 ► What happened? 
 
 At 9:30 a.m. Saturday, a pipe bomb exploded inside a garbage can in Seaside Park, N.J., along the route of a 5K charity race for the Marine Corps. That race had been delayed and no one was injured by the blast. 
 
 At 8:30 p.m. that same night, a bomb went off next to a Dumpster on West 23rd Street near Sixth Avenue. And shortly after, police found a second device — a pressure cooker with a cellphone taped to it — four blocks away, on West 27th Street between Sixth and Seventh avenues. 
 
 At 9:30 p.m. on Sunday, two men found a backpack in a garbage can in a NJ Transit train station in Elizabeth, New Jersey. When they opened it they found five pipe bombs inside and called police. Authorities later used a robot to attempt to disable the bombs and accidentally detonated one. 
 
 About an hour later, at 10:30 p.m., police stopped a vehicle on the Belt Parkway near the Verrazano-Narrows Bridge believed to belong to the family of Afghanistan-born Ahmad Khan Rahami, 28, of Elizabeth. They are questioning people inside in connection to the attacks. 
 
 Monday morning, authorities raided Rahami's home and released a wanted poster with his photo, saying they wanted to question him in connection to the attacks. Rahami was been described as armed and dangerous. 
 
 Later that morning, Ahmad Khan Rahami was arrested after a shoot-out in Linden, New Jersey - about four miles from Elizabeth — officials said. 
 
 ► What caused the blast? 
 
 Mayor Bill de Blasio confirmed that the Chelsea explosion was "an intentional act" caused by a bomb. NYPD Commissioner James O'Neill said investigators found "components indicative of an IED." 
 
 Other explosives appeared to be pipe bombs. 
 
 ► What is an IED? 
 
 An IED is an Improvised Explosive Device. A bomb. 
 
 ► Were the other devices also IED bombs? 
 
 The device found, undetonated, in the garbage can on West 27th Street was a pressure cooker with a cellphone taped to it and shrapnel inside. The NYPD used a robot to retrieve the device and then took it up to their facility in Rodman's Neck in The Bronx to examine it, police said. The device was rendered safe, and its components were sent to the FBI's facility in Quantico, Virginia. The FBI was also examining the cellphone. 
 
 The device that exploded in Seaside Park, N.J., is believed to be a pipe bomb, as are the devices found in the backpack in the Elizabeth, N.J. train station. 
 
 ► Are the incidents believed to be connected? 
 
 While investigators initially said they did not believe the incidents were the work of the same individual or individuals, they now believe they are connected. 
 
 ► Was it terrorism? 
 
 Initially, Mayor Bill de Blasio said there was no specific or credible evidence to link the incident to terrorism, but the motive for the bombing remained unclear. Gov. Andrew Cuomo said Sunday morning that there were no links to "international terrorism," but it wasn't clear whether there was a domestic terror link. He also said the incident met the general definition of an act of terrorism. 
 
 ► Were there any injuries? 
 
 Twenty-nine people were injured in the Chelsea blast and taken to area hospitals. One person was seriously injured, though none of the injuries was considered life-threatening. Eleven people were treated and released from Bellevue Hospital by Sunday morning, the hospital said on Twitter. Eight people were taken to Lenox Health Greenwich Village, five to NYU Langone Medical Center and four to Mt. Sinai Saint Luke's Hospital. Three people refused medical attention at the scene. Gov. Andrew Cuomo said all of the victims had been released from hospitals by Sunday morning. 
 
 No one was injured in the other incidents. 
 
 ► Where were the bombs found? 
 
 D. Street and Ocean Ave., Seaside Park N.J. 
 
 131 W. 23rd St. between Sixth and Seventh avenues, Chelsea 
 
 West 27th Street between Sixth and Seventh avenues, Chelsea 
 
 The NJ Transit station, Elizabeth, N.J., 
 
 ► Are those locations significant? 
 
 O'Neill said investigators were looking into whether there was any significance to the sites, but none was yet identified. 
 
 ► Is there a suspect? Has there been an arrest? 
 
 Ahmad Khan Rahami was arrested in Linden, New Jersey, on Monday morning, officials said. Rahami had posted multiple references to jihad on his website, law enforcement sources said. 
 
 ► What law enforcement agencies are involved? 
 
 The NYPD, the FBI's Joint Terrorism Task Force, the Bureau of Alcohol, Tobacco, Firearms and Explosives and other related law enforcement agencies are investigating the incident. On Sunday, Gov. Andrew Cuomo deployed 1,000 State Police and National Guardsmen to the city in an "abundance of caution." 
 
 ► Will New Yorkers see more law enforcement in the city? 
 
 Yes. The mayor and the governor have deployed police and other law enforcement officials to key sites in the city. Straphangers can expect increased bag searches in the subway, officials said. 
 
 ► How are people taking it? 
 
 New Yorkers for the most part remained calm Saturday night. Pizza orders were coming fast and furious to a Domino's pizza across from the blast site. 
 
 ► Have there been street closures? 
 
 Yes. According to the Office of Emergency Management: 
 
 • 1 Train service has resumed making normal stops at 23rd Street and 28th Street in Manhattan 
 
 • E and F Trains have resumed making normal stops at 23rd Street in Manhattan 
 
 • Northbound traffic on 6th Avenue has reopened at 14th Street 
 
 • Southbound traffic on 7th Avenue has reopened at 34th Street 
 
 • All crosstown traffic (eastbound and westbound) has reopened from West 14th Street to West 23rd Street between 5th Avenue and 8th Avenue 
 
 • West 23rd Street remains closed between 6th Avenue and 7th Avenue 
 
 ► Has public transit been affected? 
 
 Yes. Here's how: 
 
 • NJ Transit and Amtrak were suspended overnight and are expected to have delays and schedule modifications through the day Monday. 
 
 F trains are bypassing the 23rd Street station. As an alternative, take the N or the R train to 23rd Street, the MTA said. 
 
 E trains are running on the F line and bypassing the 23rd Street station. 
 
 1 trains are bypassing the 23rd and 28th Street stations. As an alternative, riders can take the A or the C trains to 23rd Street, the MTA said. 
 
 M5, M7 and M23 buses are detoured in both directions, due to NYPD Activity at 23 Street between Sixth Avenue and Seventh Avenue, according to the MTA. Detour is as follows: M5 and M7 Northbound : Via Sixth Avenue, left on 14th Street, right on Eighth Avenue, right on 34th Street, left on Sixth Avenue and regular route. M23 Eastbound: Via 23rd Street, right on Ninth Avenue, left on 14th Street, left on Fourth Avenue, right on 23rd Street and regular route.

 Here is a roundup of DNAinfo New York's coverage: ||||| (CNN) Three attacks in 12 hours -- explosions on New York and New Jersey streets and a stabbing spree in a Minnesota mall -- combined for tumultuous weekend, afflicting injury and moments of alarm and leaving investigators scrambling for answers. 
 
 As Monday's sunrise approached, New York City ramped up security not only because of the bombing that injured 29 people in Manhattan and the discovery of a mysterious device blocks away, but also because world leaders are gathering at the United Nations for debate at the General Assembly. 
 
 Questions abounded about Saturday's incidents, including: What, exactly, were the motives? 
 
 There were hints in the Minnesota attack, with ISIS claiming that a man who injured nine people in stabbings in St. Cloud before an off-duty police officer killed him was a "soldier of the Islamic State," though there was no immediate evidence he'd had contact with the terror group. 
 
 A recap of the three incidents, all of which authorities said were being investigated as possible terror acts: 
 
 • Around 9:30 a.m. in Seaside Park, New Jersey, one of three pipe-bomb-type devices that were wired together detonated in a garbage can, tearing apart the container but injuring no one; the other two didn't explode, federal law enforcement officials said. 
 
 Officials said the blast probably was timed to disrupt a Marine Corps charity run, but no one was near the blast because registration problems delayed the race. Officials said the device had a cell phone as a timer; no one has claimed responsibility. 
 
 • Around 8:30 p.m. in Manhattan's Chelsea neighborhood, an explosion rocked 23rd Street and 6th Avenue, injuring 29 people and sending panicked people scrambling for cover. A law enforcement source said it came from a device planted in or near a dumpster. 
 
 Investigators found an intact pressure cooker blocks away. New York Gov. Andrew Cuomo said the pressure cooker and the exploded device in Chelsea were similar, and other officials said both devices had cell phones as apparent timers. No one has claimed responsibility. Investigators found similarities between the explosives used in both states, according to multiple law enforcement officials, but authorities said they have not concluded the incidents are linked. 
 
 • About 9 p.m. ET (8 p.m. CT) in St. Cloud, Minnesota, a man wearing a security uniform entered Crossroads mall, made a reference to Allah and stabbed nine people before an off-duty police officer shot him dead, police said. He asked at least one person whether he or she was a Muslim before he attacked, witnesses said. 
 
 JUST WATCHED Mayor: Off-duty officer who shot attacker a hero Replay More Videos ... MUST WATCH Mayor: Off-duty officer who shot attacker a hero 01:18 
 
 Police did not immediately release the attacker's name, and CNN hasn't independently verified ISIS' claim that he was linked to the group. St. Cloud's police chief said investigators were "trying to get to the bottom of his motivations." No official has suggested ties between the mall attack and the explosions in New Jersey and New York. 
 
 NYC police presence 'bigger than ever' 
 
 New Yorkers already were going to see a big police presence in the city because of the 71st session of the UN General Assembly, about a 2-mile drive from the Chelsea blast site. 
 
 An explosion in New York City injured 29. 
 
 But Saturday's explosion means the police presence will be even more intense, Mayor Bill de Blasio said Sunday. 
 
 "You should know you will see a very substantial NYPD presence this week -- bigger than ever," he said 
 
 And Cuomo said 1,000 additional New York State Police officers and National Guard troops will be deployed to patrol bus terminals, airports and subway stations. 
 
 'This is a new era' 
 
 Saturday's incidents follow a few other mass attacks that happened on US soil in the past year, including the deadly December shootings in San Bernardino, California, and the deadly June shootings at a gay nightclub in Orlando, Florida. In both of those incidents, the attackers claimed an affinity for ISIS. 
 
 Threat of Islamist attacks alone has kept federal investigators busy -- the FBI has said that it is mounting 900 investigations of suspected Islamist militants in all 50 states. FBI Director James Comey said in July that ISIS terrorists may be dispersed in the West as the terror group loses territory in Iraq and Syria. 
 
 But Comey isn't worried just about Islamist terror threats. 
 
 "Our focus now is on a much more disparate threat that's hard to see -- unpredictable, motivated, and driven by people who are just disturbed," he said in an interview posted Friday on the FBI's website. 
 
 New York isn't the only metropolis to take notice of Saturday's attacks. On the other coast, Los Angeles' police were gearing up for two high-profile events Sunday: the Emmy Awards and the Los Angeles Rams' first home game since their return from two decades in St. Louis. 
 
 "As you wake up this morning to the troubling events in New York and New Jersey, please rest assured we have been monitoring the situation throughout the night," Los Angeles Police Chief Charlie Beck said in a statement released on Twitter. He said police had taken steps to ensure the Emmys and the football game would be safe, and asked people to be vigilant. Both events took place without incident. 
 
 US Rep. Charlie Rangel, a Democrat who represents Manhattan, told CNN that Saturday's attacks -- and a level of vigilance needed to combat them -- represent "a new norm." 
 
 "This is a new era, and everyone just has to be alert," he said Sunday.

 The off-duty police officer who killed the Minnesota attacker reflects that kind of alertness, CNN law enforcement analyst Art Roderick said 
 
 "No law enforcement officer believes they're ever off duty anymore," Roderick told CNN's Fredricka Whitfield. "I think everybody now just about carries a firearm when they're off duty from their regular law enforcement job." 
 
 In Elizabeth, New Jersey, federal and local authorities were called into action Sunday night to investigate the contents of a backpack found in a garbage can near a train trestle, according to Mayor Chris Bollwage. As a precaution, local rail and bus service was suspended. 
 
 After two men spotted the suspicious package, which had wires and a pipe but no apparent timing devices, they reported it to authorities. The FBI's bomb squad then deployed a robot to examine the devices. The suspicious package exploded after the bomb robot cut a wire in an effort to disarm the device. 
 
 Authorities do not know if the Elizabeth explosion has ties to the Chelsea bombing. 
 
 'The entire neighborhood is real scared' 
 
 Many in Chelsea were rattled by Saturday's bombing. Danilo Gabrielli, 50, was watching TV at his 23rd Street apartment about a block away from the explosion site when he heard the blast. He rushed to see what had happened and found a chaotic scene. 
 
 "We smelled something, like an intense sulfur smell, and saw smoke coming out of this building. I saw pieces of metal -- not large, but not small either. A few friends of mine saw glass there." 
 
 Gabrielli said "the entire neighborhood is real scared." 
 
 "It's a real quiet neighborhood -- not like the center of the city or the Wall Street area. It's tiny bars, where you go to grab a drink, grab a bite to eat, watch a film. We were worried." 
 
 'It's not stalling everybody that lives here' 
 
 Ryker Allen, 19, noticed the increased security presence in Manhattan. He woke up Sunday at his home in the Flatiron District, not far from the explosion, and saw "easily 100 police officers" meeting in front of his building. 
 
 He said the attack was unnerving, but people still were going about their business. 
 
 "I feel like it's something that's kind of hovering over, but it's not stalling everybody that lives here. It's not stopping anybody from getting their tasks done," he said. 
 
 Allen wasn't alone in taking it in stride. 
 
 For those trying to capitalize on the explosion: People aren't freaking out in Chelsea. People aren't in fear in the City. This in New York! — Ali H. Soufan (@Ali_H_Soufan) September 18, 2016 
 
 "For those trying to capitalize on the explosion: People aren't freaking out in Chelsea. People aren't in fear in the City," Ali H. Soufan's Twitter account read Saturday night.
– A bomb squad robot was destroyed and another had its arm blown off when one of five bombs found in a backpack near a New Jersey train station blew up early Monday. The FBI says the other four devices found will be encased in blastproof material and taken to the agency's headquarters for further investigation, the New York Times reports. The devices—which were discovered by two men who found the backpack on top of a garbage can outside a restaurant near the Elizabeth station—will be closely examined for evidence linking them to explosive devices found in New York City and elsewhere in New Jersey over the weekend. A round-up of coverage: Elizabeth Mayor Christian Bollwage says the two men thought the backpack held something of value and carried it some distance before realizing it held explosive devices and calling police, NJ.com. He says in its original location near a pub, the devices could have caused carnage. "If that pub was crowded and there was a lot of people there, it could have severely injured, killed and maimed many, many people," the mayor says. The AP reports that thousands of Amtrak and NJ Transit passengers were affected by the discovery of the device, with some stuck on trains for hours. Service has resumed but passengers in the area have been warned that they can expect delays Monday. NBC New York reports that investigators believe surveillance video shows the same man at two locations where explosive devices were found in Manhattan. Police aren't sure whether there is a link between the New York devices and those found in New Jersey. CNN reports that there is now an increased security presence in New York City not just because of the bombs, but because world leaders are gathering for the United Nations General Assembly. A law enforcement source tells CBS that investigators believe cell phones were used as triggers for both the Manhattan blast—which NY Gov. Andrew Cuomo calls "obviously an act of terrorism"—and the device that exploded before a New Jersey race to benefit Marines and sailors early Saturday. It's not clear whether a trigger was found with the Elizabeth devices. Bollwage says he's not sure his city was targeted. He suspects somebody may have just dumped the devices in Elizabeth, but he is "extremely concerned for everyone in the state and country where someone can just go and drop a backpack into a garbage can that has multiple explosives in it with no timers and then you have to wonder how many people could have been hurt." An official close to the investigation tells Reuters that all the devices involved have been crude and the level of planning appears low—but some investigators fear this was just a test. "That's what worries us," he says. "Was this some kind of test run, not just of the devices, but also of the surveillance in New York and the response?" (The FBI says it is questioning five people found in a "vehicle of interest.")
