Police used body-camera footage from an October traffic stop to track down the teen suspected of setting a homeless man on fire on a Manhattan subway train, identifying him in part based on his “distinctive mustache,” prosecutors with the U.S. Attorney’s Office said. Hiram Carrero, 18, who was caught on MTA surveillance cameras setting fire to the sleeping victim on a northbound No. 2 train at 34th St.-Penn Station on Monday, was cited by the NYPD for bicycling through a red light on Oct. 21, court documents show. Investigators compared body-cam footage recorded during the traffic stop to the footage of Monday’s arson, in which Carrero can be seen wearing the same hat, backpack and gray sweatshirt, in addition to sporting the distinctive stache in both recordings, prosecutors say.

(US Attorney's Office) Carrero was arrested in Manhattan Thursday. He was ordered held without bail Friday after prosecutors appealed a ruling by Magistrate Judge Robert Lehrburger, who at Carrero’s arraignment hours earlier, had ordered the defendant released — reportedly due to mental health issues — and given him two weeks to post $100,000 bond, a law enforcement official confirmed to the Daily News. In response to the appeal, Manhattan Federal District Judge Valerie Caproni promptly ordered Carrero remanded to custody. The teen is charged with arson resulting in the injury of another person, which carries a maximum prison sentence of 40 years, prosecutors said. “As alleged, Hiram Carrero committed a horrific arson, starting a fire inside of a New York City subway car where a victim was sleeping,” U.S. Attorney Jay Clayton said. “As a result of that arson, the victim has suffered severe injuries.” The victim is shown with his legs engulfed in flames at the 42nd St.-Times Square station, after having been set on fire one stop earlier.
