Shocking footage from a McDonald’s in Philadelphia shows an employee getting assaulted with a mop bucket wringer by a group of young men.

Authorities recently released surveillance footage of the incident, which shows the suspects dumping the mop bucket on the victim. One of the men then picks up the wringer and throws it at her face.

The Philadelphia Police Department released the footage on its YouTube page, where they asked for help identifying the suspects. The incident, which occurred last Wednesday, allegedly continued outside the restaurant.

According to authorities, the victim was struck in the face with a rock before getting punched and kicked multiple times.
