AKRON, Ohio — Postal workers who thought their coffee tasted funny had their suspicions confirmed after they set up a video camera in their break room.

A colleague has been charged with putting urine in their coffee. He was caught in the act on tape, officials said.

Thomas Shaheen, 49, a vehicle mechanic for the U.S. Postal Service, was charged Aug. 5 with two misdemeanor counts of adulteration of food or placing harmful objects in food. He has been ordered to appear in Municipal Court on Monday.

"Employees did put a video camera in, and that's how they were able to put a stop to what he was doing," prosecutor Douglas Powley said.

Shaheen's attorney did not return a call for comment.
