Footage of a violent arrest last week that has since gone viral on social media shows a police officer brutally body slamming a 17-year-old girl who was reportedly handcuffed.

The May 21 incident occurred in the parking lot of the San Bernardino Food4Less grocery at around 2 p.m., according to Najee Ali, a spokesperson for the family who spoke at a Sunday press conference outside the San Bernardino Police Department.

Police said they were called to the area on reports of a person trespassing and someone actively trying to fight other people inside the Food4Less.

Cellphone video captured the moment the teen, standing face first against the police cruiser, was lifted off her feet and viciously slammed to the ground by the officer.
