A New York City taxi cab jumped a curb in Manhattan Monday afternoon and slammed into a crowd of people after mowing down a biker on Broadway, according to city police.

The NYPD said during an afternoon news briefing that five people had been struck, three of whom suffered critical injuries. One was a bicyclist who the cab driver collided with first during a left-hand turn onto the busy street. Two females were pinned against a wall, according to authorities, and between 15 and 20 bystanders ran over to try and lift the SUV off of them.

The driver was also taken to the hospital, according to authorities.

It happened at 1186 Broadway, a few blocks away from Madison Square Park and an area frequently packed with New Yorkers and tourists alike. Police said they had obtained video evidence.
