Police have arrested the driver of a van who plowed into a pedestrian and a cyclist while driving the wrong way down a busy Hell's Kitchen Street on Saturday night.

The driver, James Mansfield, claims that he was loading high-end bicycles into his van when another man stole one and drove off down 50th Street. According to police, the driver pursued the alleged thief in his van while going westbound on 50th Street just after 5 p.m. As the van approached 9th Avenue, graphic surveillance footage shows the driver ramming the cyclist and a pedestrian, who was walking in the crosswalk at the time.

In the above video, Mansfield can be seen getting out of the car and attempting to restrain the alleged thief, before he eventually gets away. When police arrived at the scene minutes later, the 31-year-old pedestrian was unconscious, with lacerations to the head and elbow. He was transported to Cornell Medical Hospital, and is expected to survive.

The cyclist, meanwhile, had not been found as of Sunday morning. "He hit him, but the guy got up and ran away on foot, but he was badly hurt," witness Nelson Almonte told NBC News.

Mansfield has been charged with reckless endangerment, police said.
