BROOKLYN - A man riding his bicycle was seriously injured in Bed-Stuy after a hit-and-run. 

It happened Thursday around 10 p.m. at the intersection of Fulton Street and Tompkins Avenue. 

Police say they responded to the report of a man down and found a 43-year-old man lying injured in the middle of the street. He was rushed to Kings County Hospital with head injuries and was listed in critical condition. 

Police say a black colored Jeep was reported leaving the scene.

At first, police were unsure if the man simply fell off of his bike or if he was hit by the car. But after investigating, police say the man was hit by a vehicle. 

They are looking for the driver of the Jeep.
