OMAHA, Neb. (AP) — A good Samaritan has lost the tip of a finger while trying to free motorcyclists who’d been pinned under a car in Omaha.

The accident occurred Sunday afternoon in northeast Omaha. Authorities say Albert Brown and Patricia White were headed south when their motorcycle collided with westbound car that police say didn’t halt at a stop sign.

Police say Willie Parks used a car jack to rescue Brown and White from under the car. Parks severed the tip of his right index finger while freeing the couple.

They both suffered a broken leg. The car driver wasn’t injured.
