Around 100 cab drivers smashed up a Porsche in a revenge attack on Shenzhen’s Shennan Boulevard early yesterday morning (May 8), China Daily reports. At around 3 a.m. riot police arrived at the scene at the Hongling junction of Shennan Boulevard where a drunken Porsche Cayenne driver had beaten up a cab driver, inciting further violence.

The incident began when the Porsche collided with a BYD taxi. Police later found that the driver of the Porsche, Mr Chen, had a blood/alcohol level of 137mg per 100ml, which is over the legal limit.

Eyewitnesses say they saw Chen kicking the taxi driver, Mr Li, in the head ferociously; he was later hospitalized. Chen tried to drive off, but his car wouldn’t start, reports say.

A crowd of cab drivers gathered and they smashed the vehicle up and even poured beer into its fuel tank. They even tried to drag Chen, who was by then unconscious, from the back of the police car. It took riot police until 4 a.m. to disperse the crowd.
