Bach Biting Mad?

Sebastian Bach is facing multiple charges stemming from a Nov. 15 incident at a Canadian bar.

The former Skid Row frontman was reportedly hanging with friends at Riley’s Old Towne Pub in Peterborough, Ontario, when a dispute arose and he was asked to leave.

Bach allegedly smashed his wine glass against the front door when he was told he couldn’t take it for the road, and was detained by staff.

Police told the Canadian Press that during the struggle, Bach bit a staff member on the hand. Cops found a small amount of marijuana on Bach during a search.

Bach faces charges of assault, possession of a controlled substance and mischief under $5,000. The singer was due in court at press time.
