PORTSMOUTH, N.H.-- Police say a Maine teenager who left his fake ID at a grocery store after he was unable to buy beer with it has been fined and ordered to do community service.

The Portsmouth Herald reports 18-year-old Timothy Kelleher of York pleaded guilty in Portsmouth District Court to three misdemeanors: possession of false ID, misrepresentation of age to buy alcohol and unlawful possession of alcohol.

He has to pay nearly $1,000 and complete 30 hours of community service related to alcohol injuries or prevention to avoid additional fines.

A store clerk refused to sell Kelleher a 30-pack of beer on St. Patrick’s Day. Police say Kelleher swore on his way out the door and left behind the ID, which featured his name and photo.
