MCKEESPORT, Pa. -- A bizarre incident in McKeesport Thursday night involving a microwave and what was believed to be a male body part is being called a hoax.

Police in McKeesport said a woman who needed to pass a work-related drug test was the reason behind a fake penis being microwaved at a convenience store.

A clerk at the Giant Eagle Get-Go store along Lyle Boulevard told police that a man brought what appeared to be a severed penis into the store and asked her to microwave it Thursday night.

But police said the item was actually a fake, hollow penis that a woman planned to use to pass a drug test.

McKeesport Police Chief Joseph Pero said the woman's male companion had filled the device with his urine, which the woman somehow planned to pass off as hers for a drug test.

The couple stopped at the convenience store to have the device microwaved because the woman wanted the device to be warmed up to something approaching body temperature -- as part of the drug-testing ruse.

Police said they plan to charge the man and woman criminally, although the exact charges haven't been determined.

Giant Eagle officials aren't commenting on the incident.
