Several people were injured when a car drove into a street protest in midtown Manhattan on Friday, the New York City Police Department said.
The protest march was passing through the intersection of 39th Street and Third Avenue at around 4 pm EST when the car went through, said Tom Ella, who was there documenting the demonstration.
The New York Fire Department said six people were taken by ambulance to local hospitals. Police and fire officials said the injuries didn't appear to be life-threatening.
Police said the driver, a woman, was stopped near the area. She was taken into custody and was being questioned. It wasn't clear if she would face charges.
In a video captured by Ella showing the car's movements, a small group of protesters could be seen gathered around the car on 39th Street as it slowly approached the intersection with Third Avenue, with one person seemingly leaning over the front of the vehicle.
The car suddenly accelerated, knocking aside both the people who were blocking it and people who were in the intersection.
"``Suddenly you hear the engine roar, you see them accelerate,``" Ella said. ``"Just watching them actually hit people, it's traumatizing, it's horrifying".
A participant in the protest, Sofia Vickerman, of Denver, Colorado, said that when the car hit the crowd, it tossed people and a bicycle in the air.
"I hear people screaming in the front, I look behind me, the woman is plowing through," she said. "I see bodies flying".
She said the march had begun in Times Square and was aimed at drawing attention to an ongoing hunger strike by immigration detainees at a jail in New Jersey.
