Ferguson, Missouri (CNN) -- Hours after federal civil rights investigators and the FBI opened an inquiry into the death of a teenager shot by a police officer in Ferguson, Missouri, violence flared again in the St. Louis suburb. 
 
 Police Chief Thomas Jackson told CNN shots were fired Monday night in Ferguson, and police fired tear gas to disperse a crowd that had gathered in an area where looting occurred Sunday. 
 
 "Officers were brought in to quell the hostilities," he said. "Tear gas was deployed." 
 
 The Saturday-night shooting, which left 18-year-old Michael Brown dead, has fueled rising tensions in the town of 21,000 and sparked national debate. 
 
 One side says the African-American teenager was surrendering, his hands in the air to show he was unarmed, when the officer opened fire. Authorities counter that Brown had attacked the officer in his car and tried to take his gun. 
 
 After a vigil for the teen devolved into chaos Sunday when violence and looting broke out among some protesters, NAACP President Cornell William Brooks called Monday for people protesting Brown's death to do so nonviolently. 
 
 "We have seen young people giving in to violence and frustration and rage. It may be inexcusable. It is not unexpected," Brooks told reporters. "But I say to my young brothers and sisters, note the young man whose rage is your heart, note that he was nonviolent. He never got into a fight. If you want to honor his memory, honor his memory by seeking justice nonviolently." 
 
 Witnesses to Brown's shooting say he was unarmed and had his hands in the air when the police officer shot him. 
 
 Authorities tell a different story. St. Louis County Police Chief Jon Belmar says the officer tried to get out of his vehicle just before the shooting, but Brown pushed him back into his car. 
 
 Brown "physically assaulted" the officer, Belmar said, and the teen tried to get the officer's weapon. 
 
 Brown was shot about 35 feet from the vehicle, the chief said, declining to provide more details. The officer's name has not been released by authorities. 
 
 "The genesis of this was a physical confrontation," Belmar said, adding that his department has been called in to conduct an independent investigation. 
 
 The Ferguson Police Department said its cars are not equipped with dashboard cameras. 
 
 Shell casings collected at the scene were from the officer's weapon, Belmar said. 
 
 Monday, U.S. Attorney General Eric Holder said the shooting "deserves a fulsome review" by federal investigators. 
 
 "At every step, we will work with the local investigators, who should be prepared to complete a thorough, fair investigation in their own right. I will continue to receive regular updates on this matter in the coming days," Holder said in a statement. "Aggressively pursuing investigations such as this is critical for preserving trust between law enforcement and the communities they serve." 
 
 Mother: 'No violence, just justice' 
 
 The lawyer representing Brown's parents called Monday for a swift investigation. 
 
 "We want this investigation to be done fairly, and we make a demand to the Justice Department to come in and help restore trust and confidence in the process of equal justice. ... This family is very distrustful. This community is very distrustful," attorney Benjamin Crump told reporters, calling for witnesses to come forward. 
 
 Brown's parents urged people to remain calm. 
 
 "No violence, just justice," the teen's mother, Lesley McSpadden, told reporters. 
 
 McSpadden said her son recently graduated from high school and was supposed to start college Monday. 
 
 "We can't even celebrate," she said. "We've got to plan a funeral." 
 
 Standing beside the teen's family, Brooks said the NAACP is committed to determining what happened. 
 
 "We are committed to this family, committed to seeking justice, committed to being a presence, day-in and day-out," he told reporters. 
 
 Mayor calls for calm 
 
 "Obviously, the events of last night are not indicative of who we are," Ferguson Mayor James Knowles said on CNN on Monday morning, adding that Sunday night's chaos was "not constructive" and was only "bringing down the community." 
 
 St. Louis County Police said 32 people were arrested and shots were fired at police. 
 
 Monday, St. Louis County Prosecuting Attorney Robert McCulloch said charges had been filed against about 10 people in connection with burglaries of several businesses. 
 
 "What occurred last night, the mob action, we know certainly is not representative of what's going on and what the people in the neighborhood necessarily think," he said. 
 
 Flanked by several from the community Sunday, McSpadden was McSpadden was emotional as she shouted into a television reporter's microphone. 
 
 "You took my son away from me! You know how hard it was for me to get him to stay in school and graduate? You know how many black men graduate? Not many!" she said. "Because you bring them down to this type of level where they feel they don't got nothing to live for anyway! (They feel) they gonna try to take me out anyway!" 
 
 Others who gathered shouted at police. 
 
 "We will stay out here as long as you are!" they screamed at officers. 
 
 Many of the officers appeared stoic, watching young men kneel before them and raise their hands up to symbolize surrender, but one officer can be heard on video yelling back, calling protesters "animals." 
 
 Some in Ferguson are demanding that the name of the officer who shot the teenager be released. 
 
 Monday afternoon, Jackson -- the police chief -- said he plans to release the name in the next 24 hours. Authorities want to make sure the officer is in a safe location, he said. 
 
 'Lost control' 
 
 "Last night, everything lost control," Knowles said Monday. 
 
 He was asked about the officer who called protesters "animals." 
 
 "The officers did their best. They're only human," Knowles responded, adding that not every police officer present was from the Ferguson department. 
 
 Sunday's gathering became more intense as some people broke windows at a store and began taking things from it. They threw rocks and bottles. Gunshots rang out. 
 
 Antonio French, an alderman in St. Louis, said a QuikTrip gas station was looted and an ATM dragged out. 
 
 "This QuikTrip is where things started (Saturday) with this case, based on various accounts," French said. 
 
 The slain teenager and a friend were "accused of stealing gum from the store or some sort of cigarettes," the alderman said. 
 
 "People have a lot of anger and are frustrated," French said. "They don't have recourse in the system, and it happens often in this country, and it has boiled over. I think people are angry and looking for a reason to let it out tonight." 
 
 Knowles said he wants to let the independent investigation into Brown's death take its course. He plans to meet with Brown's parents soon and will meet with clergy in Ferguson and African-American leadership in the town. 
 
 Whatever the investigation's findings, "we will deal with that," he said. 
 
 Multiple gunshots 
 
 An autopsy will determine how many times Brown was shot. The medical examiner for St. Louis County, Mary Case, said Monday afternoon the autopsy is complete, but she would not give details and said St. Louis County police will release the information. 
 
 Toxicology results on Brown's body are pending. 
 
 On the number of times Brown might have been shot, Belmar has said, "It was more than just a couple." 
 
 "We don't know what happened, and there are lots of conflicting stories," Knowles said. "Unfortunately, there will have to be some time taken to understand what happened. Hopefully, we will get to an understanding, and justice will be served." 
 
 The officer who shot Brown is on paid administrative leave during the investigation and will be available to talk to county homicide detectives. 
 
 He has been with the force for six years and will be required to undergo two psychological evaluations before returning to duty, Belmar said. 
 
 Crump, who also handled the case of Trayvon Martin in Florida, said Monday that Brown's family is "devastated" and doesn't believe that the teenager got into a physical confrontation with police. 
 
 Martin, 17, was killed in 2012 by a Florida neighborhood watch organizer who was acquitted last year of murder charges. 
 
 The high-profile case sparked a heated nationwide discussion of race as well as debate over Florida's "stand your ground" law. 
 
 Monday, Crump said Brown's shooting once again highlights "the senseless death of a young boy of color at the hands of people who are supposed to protect and serve them." 
 
 "Their son was doing all the right things," Crump said. "Graduating from high school, never been in trouble. And for this to happen, for him to be killed in broad daylight ... they want answers just like everybody else in the community."

 Scattered clashes and violence had flared early Sunday morning during the first hours of the curfew, which began at midnight and continued to 5 a.m. But the trouble Sunday evening was a sharp contrast to the mood of the rest of the day. At churches across the area, ministers, the police and civil rights figures joined parishioners in trying to tamp down the anger that has followed the Aug. 9 death of Mr. Brown, 18. 
 
 In a packed sanctuary at Greater Grace Church, not far from the site of evening demonstrations, Capt. Ronald S. Johnson, the Missouri State Highway Patrol official brought in by the governor to take over security here, spoke with the cadence of a preacher as he apologized to the family of the teenager. “My heart goes out to you, and I say that I’m sorry,” Captain Johnson said. “I wear this uniform, and I should stand up here and say that I’m sorry.”

 Before a mostly black audience, Captain Johnson, who is African-American, spoke of his own “black son, who wears his pants saggy, wears his hat cocked to the side and has tattoos on his arms.” He added, “That’s my baby.” 
 
 “Michael’s going to make it better for our sons so they can be better black men,” he said, predicting that the treatment of black youths here would somehow change. “We need to pray. We need to thank Michael for his life. And we need to thank him for the change that he is going to make.” 
 
 Time and again, he won applause. But in a vivid display of the challenges faced by the authorities in this tumultuous city of 21,000 that has become the center of a national debate about race and policing, a large crowd outside continued to protest Mr. Brown’s death. The shooting of the teenager on Aug. 9 by a white officer, Darren Wilson, is the subject of inquiries by the Federal Bureau of Investigation and the St. Louis County police. 
 
 Several demonstrators held signs reading “Stop racist police killing,” while many others joined in the chant that has echoed through this city’s streets for days: “Hands up! Don’t shoot!” Hours earlier, just after a midnight curfew went into effect on Saturday, police officers dressed in riot gear and driving heavily armored vehicles engaged in a new clash with angry demonstrators. One person threw a bottle bomb that lit the street ablaze and left a lingering scent of gasoline. Before long, a police caravan, with lights flashing, began rolling slowly toward the protesters.

 “You are violating the state-imposed curfew,” an officer said over a loudspeaker. “You must disperse immediately or you’ll be subject to arrest and or other actions.” The crowd did not back down, cheering louder. Eventually a canister of tear gas was lobbed into the crowd. Smoke filled the air. Some people ran away from the police. Bottles crashed onto the pavement. Captain Johnson said the heavy police response had been prompted by reports of armed people at a barbecue restaurant. 
 
 Someone also had fired a gun toward a police car, he said. 
 
 Seven people were arrested and accused of failing to disperse, and one man was critically wounded in an overnight shooting, apparently by another protester. The authorities said the police had not opened fire. 
 
 Officials extended the curfew, which runs from midnight until 5 a.m., for another night and said they would decide each day whether to continue its enforcement.

 On Sunday, civil rights organizations called on Gov. Jay Nixon to rescind the state of emergency and the curfew in Ferguson. 
 
 The American Civil Liberties Union, the Lawyers’ Committee for Civil Rights Under Law and the N.A.A.C.P. Legal Defense Fund said in a statement that the governor’s action “suspends the constitutional right to assemble by punishing the misdeeds of the few through the theft of constitutionally protected rights of the many.” 
 
 In St. Louis, about 100 people turned out in a show of support for Officer Wilson, according to local media reports. 
 
 In churches here, the calls for calm continued. 
 
 At the Greater St. Mark Family Church in Ferguson, the state attorney general, Chris Koster, said he came to pray and grieve with the mostly African-American parishioners. “You have lost a member of your community at the hands of a member of my community,” he said. “Not just the Caucasian community, but the law enforcement community. And that is painful to every good-hearted person in this city.” 
 
 He said he feared that the armored vehicle the police used on West Florissant Avenue was a symbol of the armor that had grown between the black community and law enforcement. 
 
 “This week is a 50-year flood of anger that has broken loose in this city the likes of which we have not seen since Dr. King was killed,” he said, referring to the Rev. Dr. Martin Luther King Jr. “And I am sorry that I have not done more from the law enforcement community to break down that wall of anger, that wall of armor.”

 At the Sunday morning service at New Jerusalem Missionary Baptist Church here, about 40 people gathered. On a screen hanging above the pulpit, Jaquan Vassel, 24, the church deacon, played a video that he had seen the night before on his Facebook news feed. In it, two black men were reading from the Book of Psalms during a protest on West Florissant Avenue. “I commend them for trying to look to God,” Mr. Vassel told the congregants, “but you hear the anger in their voices.” 
 
 “They are angry at the police officers,” he added. “We have to show them how to forgive, just like God forgave us.”

 Forgiveness was also emphasized by Alonso Adams Jr., the assistant pastor of the church, who spoke after Mr. Vassel. “How many of us have killed people with our lips?” he asked. “How many brothers and sisters, white or black, have we defamed with our words?” 
 
 Mr. Adams acknowledged the anger toward the police, in particular toward Officer Wilson. But, the pastor added, “If he came into this church this morning and asked Jerusalem to forgive him, how many of you would offer up your arms?” 
 
 And later at Greater Grace Church, where cars were lined up for at least a mile, the Rev. Al Sharpton called the killing of Mr. Brown “a defining moment on how this country deals with policing and the rights of its citizens to address how police behave in this country.” 
 
 Mr. Sharpton recalled Marlene Pinnock, a black woman who was assaulted by an officer in Los Angeles this summer; Eric Garner, a black man in Staten Island who was put in a chokehold by an officer and who later died; and the death of Mr. Brown, saying: “We have had enough.” 
 
 One woman in the crowd raised a handwritten sign that equated the Ferguson Police Department with the Ku Klux Klan. 
 
 Mr. Sharpton admonished the crowd not to loot in Mr. Brown’s name. “We are not looters,” he said. “We are liberators.” ||||| Media caption As Aleem Maqbool reports, a second man was shot on Tuesday after brandishing a knife at police officers 
 
 US police say they have arrested 31 people during another night of angry protests in the town of Ferguson in the state of Missouri. 
 
 Unrest flared hours after President Obama called for calm following the fatal police shooting of unarmed black teenager Michael Brown on 9 August. 
 
 The US attorney general is due to visit Ferguson on Wednesday to meet federal officials investigating the killing. 
 
 The National Guard has been deployed to support police operations. 
 
 On Tuesday, police shot and killed a knife-wielding man four miles (6.4km) from the site of Mr Brown's killing. 
 
 Local police said witnesses reported the man behaving erratically, and that the man had come at two officers with the knife. 
 
 "The suspect turned toward officers, pulled out knife in an overhand grip, told officers to 'shoot me now, kill me now,'" said St Louis Police Chief Sam Dotson. 
 
 Missouri Governor Jay Nixon announced the National Guard deployment on Monday, in addition to lifting a night-time curfew imposed on the weekend. 
 
 The killing of Mr Brown by a white policeman in a street has inflamed racial tensions in the largely black community of Ferguson. 
 
 Media caption A new poll by the Pew Research Center has found US reaction to the police killing of Michael Brown falls along distinct racial lines. 
 
 Officer Darren Wilson shot the teenager last week after reportedly stopping him for walking in the street. 
 
 'Violent agitators' 
 
 Police Capt Ron Johnson said officers were forced to use tear gas and stun grenades on Tuesday after they came under "heavy gunfire" and were attacked with petrol bombs and bottles. 
 
 He said two people were hit by gunfire from demonstrators, insisting that officers did not use their weapons.

 Capt Johnson appealed to demonstrators to protest in the daytime to prevent a "tiny minority of law breakers" from deliberately sparking violence. 
 
 "Anyone who has been at these protests understands that there is a dangerous dynamic in the night: it allows a small number of violent agitators to hide in the crowd and then attempt to create chaos," he told journalists. 
 
 Media caption Local resident: "When they started throwing tear gas, I started running" 
 
 Those arrested include people from other states, including New York and California, Capt Johnson said. Correspondents say this suggests the protests are becoming more organised. 
 
 In an earlier statement, US Attorney General Eric Holder said he would "personally travel" to Ferguson on Wednesday to meet FBI investigators and prosecutors. 
 
 "I realise there is tremendous interest in the facts of the incident that led to Michael Brown's death, but I ask for the public patience as we conduct this investigation," Mr Holder said. 
 
 He added that the investigation into the shooting of 18-year-old Mr Brown was "a critical step in restoring trust between law enforcement and the community, not just in Ferguson, but beyond".

 Separately, President Barack Obama said he understood the "passions and anger" provoked by the death of the teenager. 
 
 But he also stressed that giving into anger "by looting or carrying guns and even attacking the police only serves to raise tensions and stir chaos". 
 
 Mr Obama said he recognised that in many communities in the US a "gulf of mistrust" existed between local residents and law enforcement. 
 
 "In too many communities, too many young men of colour are left behind and seen only as objects of fear," he said.

 Image caption Pathologist Dr Michael Baden indicates where a gunshot struck Michael Brown 
 
 Earlier, a former New York pathologist hired by Mr Brown's family performed an independent post-mortem examination. 
 
 Dr Michael Baden said on Monday he believed six bullets struck the teenager, two in the head. 
 
 "All of the gunshot wounds could have been survivable, except the one at the top of the head," he said. 
 
 Dr Baden said there were no signs of a struggle, as abrasions around the teenager's face were likely from falling to the pavement after being shot. 
 
 He also believed Mr Wilson did not shoot him at close range as there was no gunpowder residue on his body, suggesting the officer was more than 2ft (60cm) away. 
 
 Media caption Family lawyer Benjamin Crump said autopsy results backed up the witness accounts 
 
 Witnesses have said Mr Brown was shot as he held his hands up in a position of surrender, while the police and supporters of Mr Wilson have said he fired during a fight with Mr Brown. 
 
 The officer who shot Mr Brown, Darren Wilson, has been suspended with pay since the shooting. Mr Brown's family have called for his arrest. 
 
 A third post-mortem on Mr Brown was conducted by the US justice department on Tuesday, in addition to examinations by Dr Baden and St Louis county officials.

 Police: Protesters threw Molotov cocktails before police shot tear gas toward them 
 
 Michael Brown was shot at least six times, according to the preliminary results of a private autopsy that his family requested. 
 
 The independent autopsy was conducted by high-profile pathologist Michael Baden. Baden testified in the O.J. Simpson, Phil Spector and Drew Peterson murder trials. 
 
 Family attorney Daryl Parks did not provide additional details about the preliminary results. 
 
 However, the New York Times, reporting on the same independent autopsy, reported that two of the bullets struck Brown in the head. The other four struck him in the right arm -- and all six were fired into his front. 
 
 "This is bound to escalate tensions," the Rev. Jesse Jackson told CNN. "This is a very provocative report." 
 
 Even before the release of this latest information, the St. Louis suburb of Ferguson has been a racially charged tinderbox. 
 
 Clashes once again 
 
 Late Sunday night, a day of peaceful protests devolved into a night of gunfire, Molotov cocktails and tear gas . 
 
 Officers fired tear gas into a crowd of hundreds of protester, including children, who were marching toward a police command post despite an impending midnight curfew. Authorities also struck at least one defiant protester with rubber bullets. 
 
 St. Louis County police said several protesters had thrown Molotov cocktails toward the officers before authorities shot tear gas toward them. 
 
 The violence escalated through the night as shots were fired toward police. Officers had to take up a defensive position behind vehicles. 
 
 "That is a lie. It was no fight, it was no shots fired," a very upset protester, Lisha Williams, told CNN. "The only ones who fired was police. All we did was march to the command center to fall to our knees and say, 'Don't shoot.' And they started shooting." 
 
 The scene was a far cry from a packed church earlier Sunday, where hundreds of people gathered for a two-hour rally demanding justice for Michael Brown, an unarmed black teenager shot dead eight days ago by a white police officer. 
 
 "I'm astonished at this reversal of mood," Jackson said. "The mood was so positive." 
 
 Cousin: Brown killed without reason 
 
 A cousin of Brown told the church audience that Brown was killed without reason. 
 
 "What I want y'all to remember is that Michael Brown was not just some young black boy. He was a human being ... ," Ty Pruitt said. "He was not a suspect. He was not an object. He was not an animal. But that's how he was killed." 
 
 Michael Brown's parents -- Lesley McSpadden and Michael Brown Sr. -- appeared on stage at the rally at Greater Grace Church with attorney Benjamin Crump but didn't address the audience. 
 
 "What we're really asking for is simple justice," Crump said. "We're not asking for anything extraordinary. They just want what anybody else would want if their children were shot down in broad daylight." 
 
 Crump said there would be an independent investigation in addition to the federal and local probes already under way. 
 
 Missouri State Highway Patrol Capt. Ron Johnson spoke to the 1,300 people in the congregation and said he had a heavy heart.

 "The past 24 hours have been tough for me," said Johnson, who took over security in the town on Thursday after what many saw as an overly aggressive police response by the local authorities. Johnson said he met with members of the Brown family and was moved to tears. 
 
 Protests had turned violent on Saturday night as well after a curfew began. One male was shot overnight Saturday, authorities said. It was unclear how old he was or who shot him. The victim was in critical condition Sunday. 
 
 Officials said state highway patrol officers didn't fire any shots. They did fire tear gas to get to the wounded victim, Johnson said early Sunday.

 Brown was shot to death August 9 by a police officer after a confrontation as the teen walked down the street. Accounts of exactly what happened when Officer Darren Wilson stopped Brown vary widely. 
 
 Witnesses said they saw a scuffle between the officer and Brown at the police car before the young man was shot. Police said Brown struggled with the officer and reached for his weapon. 
 
 Several witnesses said Brown raised his hands and was not attacking the officer. 
 
 U.S. Attorney General Eric Holder has approved another autopsy on Brown's body, the Justice Department said. The autopsy will be conducted by a federal medical examiner.
– The St. Louis suburb of Ferguson, Mo., was the scene of another evening of rioting and unrest last night as largely young, black crowds faced off against a mostly white police force that reportedly responded with tear gas, reports the Los Angeles Times. But the family of slain teenager Michael Brown, 18, asked the community to remain peaceful so that no more lives will be lost. "No violence, just justice," his mother told reporters. While some demonstrators got down on their knees with their hands raised in symbolic surrender, others shouted, "We will stay out here as long as you are!" Some of the police did not appear to respond to the taunts, while others were caught on camera calling the protesters "animals," reports CNN. Two very different stories have emerged surrounding the shooting of Brown, who was set to start technical college yesterday, two days after he was killed, reports CNN in another review of the details. While the police report suggests Brown, who'd been walking with a friend in the street, attacked an officer in his police car and tried to take his gun when the officer told him to use the sidewalk, witnesses say the officer fired after a verbal altercation and that as Brown turned away and fled he was shot once, then at least twice more after he put his hands in the air. Police have not disputed that Brown was unarmed. The police officer who shot him, a six-year veteran of the force, is on paid administrative leave. USA Today reports that one of Brown's last Facebook posts included the words: "if I leave this earth today, at least youll know i care about others more then I cared about my damn self." The FBI, meanwhile, has taken over the investigation.
