A road-raging driver slashed another man with a box cutter, snatched his keys and then hit him with a car in Greenpoint Tuesday, police say.

Witnesses took cellphone video of the altercation at the intersection of Norman Avenue and McGuinness Boulevard.

It shows a brief scuffle between two men, one of whom appears to slash and strike the other.

Then police say the suspect swiped the keys from the victim's ignition before jumping into his own car, pinning the man against another vehicle and fleeing the scene.

The victim was transported to the hospital with bruises to his hip and cuts to his hand.

Police say no arrests have been made and they are still looking for the suspect.
