A man was beaten unconscious by a group of assailants during an altercation at a ‘side show’ in California over the weekend, according to reports.

The shocking incident unfolded on Sunday in Oakland.

After ‘street racers’ took over an intersection and began performing dangerous stunts, one fed-up resident tried to stop the illegal activity, KTVU reports.

Footage circulating on social media shows the apparently exasperated man throw an object at a car as the driver does a doughnut in the street.

Suddenly, the man is attacked by multiple assailants who knock him to the ground and savagely beat him as a crowd gathers.

The victim is kicked and punched repeatedly by hooded and masked thugs as witnesses cheer and record with their phones.

As the man lies motionless and bloodied, a suspect grabs him and pulls his pants down while launching another round of kicks.

Eventually, the mob disperses and the victim is left apparently unconscious on the sidewalk as the street stunts continue.

One bystander can be seen putting the victim’s head inside a bucket and snapping a photo.

It is unclear if any suspects have been apprehended or if authorities are investigating the incident at the time of this writing.

During a similar episode earlier this year, a family trapped by a mob on an Oakland street was robbed and their vehicle badly damaged during a confrontation, reports indicate.

Illegal stunts known as a “side shows” or “street takeovers” are happening with increasing frequency in lawless U.S. cities.

Last month, traffic across the iconic Bay Bridge connecting San Francisco and Oakland was brought to a halt when around 100 thugs on motorcycles blocked all westbound lanes.

Infowars has been reporting on the surge of crime in many U.S. cities.
