CHP received reports about a sideshow on Highway 101 in San Francisco. A little later they received reports of an alleged fight with a motorist.
The group of dirt bikers appear to harass the Lyft driver and then they seem to punch and kick the driver before they take off.
When officials arrived the Lyft driver was being treated by an ambulance and the victim reportedly suffered a broken leg.
The CHP is reviewing the video and asking the public for information about the event.
