A teenager was served instant karma as he was forced to quickly flee after hurling chairs at two restaurant workers as a 'gang of 30 teens' watched on.

A shocking video has emerged online of about 30 youngsters attacking a family restaurant in the seaside Kent town of Broadstairs.

The 59-second clip shows a gaggle of yobs storming towards a Italian restaurant, Sardinia, as two staff members appear at the workplace's doorway.

Another youth then pushes one of the men as tensions escalate with another teenager picking up a chair and launching it towards a glass pane.

As another unidentified item is hurled through the air, the young man picks up a chair and throws it at a staff member, armed with a black chair.
