According to a news website, the police said that the man identified as “Dong” ran into a road near a bus station and jumped in front of a woman’s car.
The man then hopped on the hood and starting pounding on the woman’s windshield, a major newspaper reported.
When the woman, identified as “Du,” got out of the car, the man tackled her and started chewing on her face.
Photographs posted online appeared to show the deranged bus driver straddling the helpless woman on the ground.
Witnesses said that they tried to stop the attack, but Dong had gone “crazy” and was able to overpower them.
Police eventually pulled the maniac off Du and cuffed him, the report said.
The woman was taken to a local hospital with tears to her lips and nose and would need plastic surgery to repair her face.
The police said the man drank heavily during lunch with friends before the attack.
