The beer ad attracted attention — but not in the way Pabst Blue Ribbon had intended.

A bartender called police because he thought a blinking red light was a bomb, resulting in the evacuation of 35 people from a resort hotel.

Guests were allowed back in their rooms less than an hour later, after a sheriff's officer determined the light was part of a Pabst Blue Ribbon beer ad. The ad was suction-cupped to the window of the Sam Snead restaurant in Swan Lake Resort.

The bartender called authorities about the suspicious flashing light at 12:30 a.m. Monday, and guests were evacuated about six minutes later, said Doug Leedke, general manager of the resort in Plymouth, 25 miles south of South Bend.

The false alarm is a sign of the times, Leedke said.

"Our employee saw something unusual and reported it," he said.
