Police have released surveillance video of a hit-and-run driver who struck a bicyclist in Harlem last week. The 57-year-old cyclist is currently in critical condition.

According to the NYPD, at around 9:48 p.m., officers responded to a 911 call about a bicyclist who was struck near the intersection of 145th St and Lenox Avenue and found a 57-year-old man, unconscious and unresponsive with head injuries, lying in the road. Police say that the driver of a red car "was traveling westbound in the left lane on West 145th Street when the bicyclist was stopped in the middle of the roadway attempting to cross West 145th from north to south."

The motorist then hit the cyclist, "causing him to mount the hood and fall to the pavement," while the bicycle itself struck the window of a 2006 Honda Odyssey that was passing by on 145th Street.

The driver of the red car fled while the driver of the Odyssey remained on the scene. Here's video of the red car:

Witnesses said the red car appeared to be speeding.
