Los Angeles — A brutal beating in Los Angeles is caught on tape.

Now, police are looking for answers.  They say someone in a nearby car recorded the fight on a cell phone.

The video shows a fist-fight between three men along Interstate 5.  But the fight quickly escalates and one man ends up one the ground as the others kick him in the head. The suspects then drive off.

Police say it was a violent case of road rage. Now, they're asking for help finding the people involved.

"At this point in time, we are seeking the public's assistance in not only identifying and speaking with the individuals involved in the incident, but we would also like to speak to any witnesses who may have seen this incident, video-taped this incident and or have any information that would assist in us furthering our investigation."

The video was first uploaded to YouTube and then deleted.

It re-surfaced on LiveLeak on Monday.
