A traveler attempting to hide a prohibited substance inside a prohibited item — and then tucking them into his groin area — was quickly caught by TSA officers this week.

Authorities say a TSA checkpoint scanner alerted them that the man had been hiding something under his clothes.

An Orangeville, Pa. man was arrested on Monday after he was, allegedly, found with a shotgun shell stuffed with methamphetamine hidden in his groin as he attempted to enter the Philadelphia International Airport.

The Columbia County man was flagged at a checkpoint scanner on Monday and the shotgun shell was found under his clothes in his groin area, officials said.

TSA officers at the Philadelphia International Airport said the shotgun shell contained an illegal item — but not what you’d expect to find.

A Pennsylvania man was arrested after TSA agents found an altered shotgun shell filled with methamphetamines concealed in his groin at a security checkpoint.
