FORT PIERCE, Fla. - Sheriff's investigators say a man accused of setting fire to a Florida mosque confessed and said he was embarrassed. 
 
 According to a St. Lucie County Sheriff's Office arrest affidavit released Thursday, 32-year-old Joseph Schreiber was developed as a suspect in the fire Sunday at the Islamic Center of Fort Pierce in part because of a tip. 
 
 Detectives say that after his arrest Wednesday, Schreiber admitted setting the fire, said he had no intention of hurting anyone and was embarrassed to have committed the crime. 
 
 Schreiber was ordered held without bail earlier Thursday. The public defender's office had no immediate comment. 
 
 Schreiber was arrested in connection with the fire at the Islamic Center of Fort Pierce, which sustained extensive damage in a blaze set late Sunday, on the 15th anniversary of the 9/11 terror attacks. 
 
 The fire also coincided with the Muslim holiday Eid al-Adha. 
 
 Schreiber was arrested Wednesday by St. Lucie County Sheriff's Office investigators, and charged with arson after a tip came in to deputies Tuesday night identifying Schreiber as the suspect in the mosque arson. 
 
 Deputies said they searched Schreiber's home and also found a motorcycle matching the one that was seen in surveillance video, speeding away from the fire. 
 
 They also found Schreiber posted anti-Islamic comments on social media, deputies said. 
 
 "There is anti-Islam propaganda, and that corroborates our fear that it has to do with the Islamic community," said Maj. Dave Thompson, with the Sheriff's Office. 
 
 News 6 found out Schreiber has been in and out of prison, serving a combined 6 1/2 years for theft. 
 
 Because the arson may be a hate crime, investigators said he could face a first-degree felony for igniting the mosque, which could land him back in prison for 30 years. 
 
 If he's found to be a habitual offender, he could face life in prison. 
 
 The FBI is continuing its investigation to see if Schreiber could face federal charges.

 The case is being prosecuted as a hate crime under Florida law, and the suspect, Joseph Michael Schreiber, 32, faces at least 30 years in prison if convicted of committing Monday’s arson attack, according to the St. Lucie County Sheriff’s Office. 
 
 Schreiber is accused of starting the blaze that heavily damaged the Islamic Center of Fort Pierce, a place of worship for gunman Omar Mateen before he shot 49 people to death and wounded 53 others at a gay nightclub in June. 
 
 Mateen himself was killed by law enforcement officers at the end of the shooting in Orlando, about 100 miles (160 km) northwest of the Atlantic coast town of Fort Pierce. 
 
 Fire erupted at the mosque at about 12:30 a.m. EDT on Monday, coinciding with one of the holiest of Muslim holidays, Eid al-Adha, or the Feast of Sacrifice, and authorities immediately branded it an arson attack. 
 
 No one was inside the building at the time, but the blaze forced the congregation to hold prayer services elsewhere. 
 
 The St. Lucie County Sheriff’s Office told reporters afterward that surveillance video showed a man riding up to the building on a motorcycle, getting off the bike and approaching the mosque with a bottle of liquid and papers moments before flames erupted. 
 
 At a news conference announcing an arrest on Wednesday, Sheriff’s Major David Thompson said Schreiber owns a motorcycle like the one seen in the video. Thompson said tips from the public led investigators to the suspect and his home in nearby Port St. Lucie, where a search turned up additional evidence tying him to the crime. 
 
 An examination of Schreiber’s social media account also uncovered “multiple anti-Islamic posts and comments,” Thompson said. He did not elaborate. 
 
 But a Facebook page apparently belonging to the suspect - established under his name with photos resembling his booking photo - include a message posted on July 12 that said “ALL ISLAM IS RADICAL, and should be considered TERRORIST AND CRIMANALS” written in capital letters with several mispellings. 
 
 Schreiber was arrested without incident on Wednesday while walking along a sidewalk in Fort Pierce, Thompson said. 
 
 Schreiber, who was being held without bond, was still being questioned by police following his arrest. He was expected to make his first court appearance on Thursday. It was not clear if he had obtained legal representation.

 He has been charged with arson, and his status as a “prison release re-offender” qualifies him for a mandatory minimum prison sentence of 30 years if convicted. And as a “habitual felony offender” whose criminal record includes armed robbery, Schreiber also would be eligible for a life term, police said. 
 
 Federal authorities are also investigating the fire for any potential violations of federal law, U.S. officials said. 
 
 The Fort Pierce Islamic Center has reported numerous threats of violence and intimidation since it was identified publicly as Mateen’s place of worship. In June a motorcycle gang circled the property and shouted at its members, and in July a Muslim man was beaten outside the mosque. ||||| The parents of a 23-year-old charged with a hate crime for an arson fire at a California mosque described their son as a loner who might have some type of mental issue, but said if he committed the crime he will have to face the consequences. 
 
 No one was hurt in Friday's fire at the Islamic Society of Coachella Valley, about 75 miles away from the scene of last week's terror attack in San Bernardino, but the building was damaged, officials said. 
 
 Carl Dial was arrested late Friday and charged with arson, commission of a hate crime and burglary, the Riverside County Sheriff's Department said. He is being held in lieu of $150,000 bail.

 "We will supply him with money for the commissary. We have no plans to bail him out. He's an adult," Dial's father, John Dial, told NBC News Saturday. "We both said right there, we said to him, I hope you like reading books, because you're in it for the long haul. He's a man." 
 
 John Dial said his son is innocent until proven guilty, but, "If he's charged with this, he's going to be responsible, as an adult," he said.

 The intentionally set fire at the mosque occurred a little more than a week after a husband and wife who authorities believe were radicalized opened fire on a holiday luncheon for county workers in San Bernardino, killing 14 people. 
 
 A man at the mosque told NBC Los Angeles that he heard an explosion before the fire. Police have not said how the fire was set. 
 
 "As far as we're concerned, it is an act of terrorism," Reymundo Nour, acting imam at the mosque, said. "The individual targeted us, we believe that it was targeted." 
 
 Carl Dial recently moved in with his brother and his brother's wife, his parents said. He was taking classes at a local college, they said.

 John Dial saw Carl early Friday, before the fire broke out at the mosque around noon. His son had a backpack and he assumed he was going to class. John Dial saw his son later, before police arrived, and nothing seemed amiss, he said. 
 
 Sheriff's deputies arrived at the home of Carl Dial's parents at around 7 p.m. Friday and interviewed them. "The officers asked me, 'Is your son capable of this. And I said anybody is capable of anything at any time," John Dial said. 
 
 Dial's father said his son struggled socially. Carl Dial's demeanor took an anti-social turn around 2000, and his father said if his son committed the arson he believes some type of psychiatric ailment might be to blame. Carl Dial had seen mental health professionals while younger, he said. 
 
 "He was caught up in social media. Social media has produced people like my son, without person-to-person contact," John Dial said. "I believe he was lacking in social skills." 
 
 Meanwhile, an online fundraising effort to help the families of the 14 people killed in San Bernardino, titled "Muslims United for San Bernardino Families," had raised more than $203,000 by Saturday night. 
 
 Reporting by NBC Producer Jessica Roe
– Police have arrested a suspect in the fire that left a 100-square-foot hole in the roof of a Florida mosque occasionally attended by Pulse nightclub shooter Omar Mateen, WKMG reports. According to Reuters, 32-year-old Joseph Schreiber is believed to be behind Sunday's arson at the Islamic Center of Fort Pierce. Scrhreiber was caught based on tips and surveillance video, the Palm Beach Post reports. The arson charge against Schreiber carries a hate-crime enhancement. Schreiber has been arrested at least 11 times since 2003 and spent time in prison in 2008 and 2010 for theft. As a "prison release re-offender," he faces a mandatory minimum sentence of 30 years. He could get life in prison if convicted as a "habitual felony offender." Police say Schreiber made anti-Islamic posts to social media. The Post quotes one such post, which reads: "ALL ISLAM...should be considered TERRORIST AND CRIMINALS and all hoo participate in such activity should be found guilty of WAR CRIM." No one was injured in the arson, and it's unclear if the mosque was targeted because Mateen went there.
