Police in Pittsburgh are looking for a man who called a branch of KFC pretending to be a policeman and warning of a robbery.

The man is said to have called the fast food restaurant and told a manager that staff should cooperate and allow police to arrest the thief when he left.

The robber showed up a few minutes later, just as the caller said, but police never arrived. The robber, armed with a long-barreled black gun, took off with about $200
