UPDATE: Police Identify Brooklyn Subway Shooter As Frank R. James, Was On FBI Terror Watch List

NEW YORK -- Officials say 10 people were shot and 13 more injured when gunman set off smoke bombs and started shooting on board a Brooklyn subway Tuesday morning.

It happened around 8:24 a.m. on a Manhattan-bound N train in Sunset Park.

The gunman fired 33 shots from a Glock 17 that jammed, preventing further injury, police said.

Police identified Frank R. James, 62, of Philadelphia as a person of interest in the case. They say James rented a U-Haul van that might be connected to the shooting.

"We are endeavoring to locate him to determine his connection to the subway shooting, if any," NYPD Chief of Detectives James Essig said.

Police recovered a bag filled with smoke bombs, hobby fuse, a hatchet as well as gasoline and a key to the U-Haul van in the subway.

The police commissioner also said they found what they called "concerning posts" connected to James. Sources say the posts expressed displeasure and disgust with New York City, Mayor Adams and homelessness.

Because of the posts, they have increased the mayor's security.

Police say a man wearing a utility vest detonated two smoke bombs inside the moving car.

"The train at that time began to fill with smoke. He then opened fire, striking multiple people on the subway and on the platform," NYPD Commissioner Keechant Sewell said.

Yav Montano was on board the train when he heard gunshots.

"I just hid. I moved myself out the way. I tried to make space for this elderly lady, who even handed me her little pepper spray from her purse just in case something happened," Montano said. "Like, she gave it to me out of her purse and said, 'Use it, just in case.' That's how desperate people were."

Video from inside the train shows the chaos as a commuter bangs on the door of a subway car, desperately trying to escape, but the door to the next car was locked.

"There was a lot of blood trailing on the floor, and then thank goodness the train moved within a minute or I don't know what might have happened if we were stuck there for long," Montano said.

Investigators say the gunman, who is described as a Black male, 5-foot-5 with a heavy build, emptied several magazines' worth of ammunition. Police later found a Glock-like handgun inside the 36th Street station.
