A shocking new video is bringing up an issue with some troubled history in southern California — accusations of excessive force and police brutality. Here's how KABC described the incident.

"An arrest so violent, it is hard to watch ... She started to walk down the on-ramp and then turned around and came back up and crossed lanes of traffic, endangering herself and the motoring public." (Via KABC)

Police say it happened just before 6 p.m. July 1 near an on-ramp on I-10. KCBS reports the California Highway Patrol officer punched the woman more than 10 times while he was sitting on top of her.

According to KNBC, the police officer involved in the video has been put on paid administrative leave. The highway patrol would not identify the officer.
