A driver lost control of his car early Wednesday morning and slammed into several parked vehicles, which led one car owner to exit his nearby home and attack the motorist, police said.
The 58-year-old driver was traveling on the 2100 block of 58th Street, near Lebanon Avenue, in the Overbrook section of Philadelphia around 3 a.m. when he struck a parked car head-on, authorities said.
The impact caused a chain-reaction crash, which damaged at least one other parked vehicle.

The owner of one of the parked vehicles -- who was inside a nearby Overbrook home -- heard the accident, came outside and spotted the driver responsible, officials said.
The car owner then assaulted the driver, hitting him in the face with the butt of a gun multiple times, police said.
The 58-year-old driver suffered injuries from both the crash and the attack, and authorities transported him to the Hospital of the University of Pennsylvania.
It is unclear what condition he is in.
An investigation is underway.
