NEW YORK: A gunman in a gas mask and construction vest set off smoke grenades and fired a barrage of bullets in a rush hour subway train in Brooklyn, wounding at least 20 people on Tuesday (Apr 12), authorities said.
Police were trying to track down the renter of a van possibly connected to the violence.
Chief of Detectives James Essig said investigators were not sure whether the man, identified as Frank R James, 62, had any link to the subway attack.
Authorities were looking at his apparent social media posts, some of which led officials to tighten New York Mayor Eric Adams' security detail. Police Commissioner Keechant Sewell called the posts “concerning”.
The attack turned the morning commute into a scene of horror: A smoke-filled underground car, an onslaught of at least 33 bullets, screaming riders running through a station, bloodied people lying on the platform as others tended to them.
In the train, Jordan Javier thought the first popping sound he heard was a textbook dropping. Then there was another pop, people started moving toward the front of the car, and he realised there was smoke, he said.
When the train pulled into the station, people ran out and were directed to another train across the platform. Passengers wept and prayed as they rode, Javier said.
“I’m just grateful to be alive,” he said.
Five gunshot victims were in critical condition but expected to survive. At least a dozen people who escaped gunshot wounds were treated for smoke inhalation and other injuries.
Sewell said the attack was not being investigated as terrorism, but that she was “not ruling out anything”. The shooter's motive was unknown.
Sitting in the back of the train's second car, the gunman tossed two smoke grenades on the floor, pulled out a Glock 9mm semi-automatic handgun and started firing, Essig said.
He said police found the weapon, along with extended magazines, a hatchet, detonated and undetonated smoke grenades, a black garbage can, a rolling cart, gasoline and the key to a U-Haul van.
That key led investigators to James, who has addresses in Philadelphia and Wisconsin, the detective chief said. The van was later found, unoccupied, near a subway station where investigators determined the gunman entered the train system, Essig said.
Rambling, profanity-filled YouTube videos apparently posted by James are replete with Black nationalist rhetoric, violent language and bigoted comments.
One, posted Apr 11, criticises crime against Black people and says drastic action is needed to change things.
A Feb 20 video says the mayor and governor’s plan to improve safety in New York City’s subway system “is doomed for failure” and refers to himself as a “victim” of the mayor’s mental health programme.
Investigators believe the shooter's gun jammed, preventing him from continuing to fire, said two law enforcement officials who were not authorised to discuss the investigation and spoke on condition of anonymity.
The attack unnerved a city on guard about a rise in gun violence and the ever-present threat of terrorism.
It left some New Yorkers jittery about riding the nation's busiest subway system and prompted officials to increase policing at transportation hubs from Philadelphia to Connecticut.
The Metropolitan Transportation Authority announced last fall it had installed security cameras in all 472 subway stations citywide, saying they would put criminals on an "express track to justice”.
But cameras were not working at three stations where police went to look for evidence on Tuesday, Essig said.
MTA system chief Janno Lieber told TV interviewers he did not know why the cameras malfunctioned.
A riders' videos show a person in a hooded sweatshirt raising an arm and pointing at something as five bangs sound.
Rider Juliana Fonda, a broadcast engineer at WNYC-FM, told its news site Gothamist that passengers from the car behind hers started banging on the connecting door.
“There was a lot of loud pops, and there was smoke in the other car,” she said. “And people were trying to get in and they couldn’t, they were pounding on the door to get into our car.”
As police searched for the shooter, Governor Kathy Hochul warned New Yorkers to be vigilant.
“This individual is still on the loose. This person is dangerous,” the Democrat said at a news conference just after noon.
After people streamed out of the train, quick-thinking transit workers ushered passengers to another train across the platform for safety, transit officials said.
High school student John Butsikaris was riding that other train and initially thought the problem was mundane until the next stop, when he heard screams for medical attention and his train was evacuated.
“I’m definitely shook,” the 15-year-old said. "Even though I didn’t see what happened, I’m still scared, because it was like a few feet away from me, what happened.”
In Menlo, Iowa, President Joe Biden praised "the first responders who jumped in action, including civilians, civilians, who didn’t hesitate to help their fellow passengers and tried to shield them”.
Adams, who is isolating following a positive COVID-19 test on Sunday, said in a video statement that the city "will not allow New Yorkers to be terrorised, even by a single individual".
New York City has faced a spate of shootings and high-profile bloodshed in recent months, including on the city’s subways. One of the most shocking was in January, when a woman was pushed to her death in front of a train by a stranger.
Adams, a Democrat a little over 100 days into his term, has made cracking down on crime - especially in the subways - an early focus of his administration, pledging to send more police officers into stations and platforms for regular patrols.
It was not immediately clear if any officers were in the station when the shootings occurred.
“It is going to take the entire nation to speak out and push back against the cult of death that has taken hold in this nation,” Adams said by video on Tuesday night.
