NEW YORK (PIX11) — Police took Frank R. James, the 62-year-old alleged shooter in a Brooklyn subway attack that left 10 people wounded by gunfire and more than a dozen others injured, into custody on Wednesday, sources said.

Though Mayor Eric Adams announced James had been upgraded from a person of interest in the case to a suspect, the NYPD have not yet provided an update on the change in their investigation from Tuesday. The NYPD was set to share new details on the shooting at 2 p.m.

Police had zeroed in on James because of a U-Haul key left at the scene of the shooting. James had rented the U-Haul, which was found in Brooklyn hours after the attack.

Here are five things we know about James:

  • James posted social media videos decrying the U.S. as a racist place awash in violence and recounting his struggle with mental illness. His profanity-laden videos are replete with violent language and bigoted comments, some against other Black people
  • The gun James allegedly used was purchased at a pawn shop — a licensed firearms dealer — in the Columbus, Ohio, area in 2011, a law enforcement official who wasn’t authorized to discuss the investigation said on condition of anonymity
  • James has ties to Philadelphia and Wisconsin
  • Investigators believe James drove up from Philadelphia on Monday and have reviewed surveillance video showing a man matching his physical description coming out of the van early Tuesday morning
  • Police described the suspected gunman as being around 5 feet, 5 inches tall. The man weighs around 175-200 pounds. He was last seen wearing a gas mask and a construction vest. Police initially said the vest was green, but later officials said it was orange. The man also had on a gray, hooded sweatshirt.
