VIDEO: Enraged driver attacks vehicle with sledgehammer

PHILADELPHIA - (NBC) - Surveillance video caught the moment a man used a sledgehammer to smash another vehicle and attack a passenger Tuesday in Philadelphia

It happened in the parking lot of a business around 1:30 p.m.

Video shows a man gets out of a red pickup truck while holding a sledgehammer, then smash the driver's side window of a sport utility vehicle before hitting the SUV three more times.

As the vehicle drives away, a man falls out of the passenger side. The vehicle stops and the man limps toward it.

The man with the sledgehammer then strikes the passenger as well as the vehicle again.

One witness said he heard the attacker yell out “you're cheating with my girlfriend.”

Police said they can't investigate it any further until a person involved with the incident comes forward.
