PITTSBURGH (AP) – It took a bomb-sniffing dog to figure out that a brown paper bag left in the bathroom of a government office building was just lunch.

The suspicious bag – containing a salad from a bagel shop – prompted security guards at the downtown building to evacuate the office of Allegheny County Executive Dan Onorato and close a main courthouse entrance. The lockdown Tuesday lasted about an hour.

The bag was found in a women’s bathroom on a shelf under a sink. A sheriff’s deputy arrived with a bomb-sniffing dog and quickly discovered there was nothing explosive about the salad.

“It was just strictly a precaution,” County Manager Jim Flynn said. “I don’t think it was a real threat.”
