George Austin was ejected from Ma Murphy’s pub in Morecambe on Christmas Day 2009 after assaulting an elderly customer. Once outside, he assaulted a second man and bit off a section of his ear.
Austin, 25, of Lymm Avenue, Lancaster, pleaded guilty to a section 20 wounding offence and common assault at an earlier hearing at Preston Crown Court.
Appearing at court on Friday, he was jailed for 12 months.
“Austin was told to leave the pub after punching an elderly gentleman and then carried on his violent behaviour outside," says DC Jon Shaw of Lancashire Police.
"His attack has left his second victim permanently disfigured and I am pleased that he received a custodial sentence as it sends out a strong message that such acts of violence will not be tolerated and will be dealt with robustly."
