Times Square in New York City was blocked off after a driver hit pedestrians, killing one and injuring 22.
O'Neill revealed that Rojas had been arrested twice in NY - in 2008 and 2015 - for drunken driving.
A speeding auto struck sidewalk pedestrians in New York City's Times Square on Thursday killing one and injuring several others, multiple outlets are reporting.
In one image, Marla can be seen holding up a women's phone just a few feet away from the police tape marking off the scene where a teenager was killed just an hour before, as the three smile for the camera. Rojas is now at a facility undergoing a drug and alcohol test. He was visibly struggling as police officers caught him and dragged him back to a cop auto.
NYPD Commissioner James O'Neill said Rojas had two prior DUI arrests.
"Based on the information that we have at this moment, there is no indication that this was an act of terrorism", mayor Bill de Blasio said. Three more were in serious condition.
Before striking pedestrians, the auto was "out of control", an emergency management official said.
The driver, a 26-year-old man from the Bronx, mounted a sidewalk at Seventh Avenue and 42nd Street in Manhattan and drove at a "high rate" for several blocks, striking pedestrians along the way, police said.
Witnesses described a harrowing scene that started with screeching tires and ended with screams, panic and a fiery crash at one of the world's most visited sites.

"He didn't stop", said Asa Lowe, of Brooklyn, who was standing outside a store when he heard screaming. She bolted across the street. Then the next thing I know it went straight down to 45th. At first, I thought someone was intentionally doing it. "I've never witnessed a man so irate, so full of rage and I never feared for my life this way". Up to 20 people might be injured and rammed into a crowd of people. Magdy Tawfik, a hot dog vendor whose stand was near the corner, said the vehicle had hit three people there.

When Long went outside and looked in the direction the vehicle had gone, she saw at least six people lying on the ground, including a woman lying face-down with blood pouring from her head. "I'm so freaked out!" the daughter said. "I saw a gentleman underneath the vehicle, and another gentleman was pulling him out, and it was a real mess".
"It looked like he was trying to hit people". I'm not saying that we haven't been doing a good job; clearly we can do more, where this might not have happened.
