A passenger on a Delta Airlines flight from Minneapolis to Salt Lake City is being investigated for exposing himself.

Apparently peppermint only makes your breath fresh and clean.

The FBI is investigating whether a man who exposed his genitals on an airplane last year accidentally got peppermint-scented pain reliever on his penis, according to a Smoking Gun report.

A female passenger told a member of the crew that Stuart Ronald Clarke, 48, exposed his genitals during a flight from Minneapolis to Salt Lake City, according to a search warrant application filed Wednesday in U.S. District Court.

Clarke told airport investigator Allen Christensen, a member of the FBI Joint Terrorism Task Force, that he had a headache before departing on his trip and rubbed the oil on his head in an effort to take away the pain. During the Delta flight, he said he went to the bathroom and inadvertently got some of the peppermint residue on his private parts. When he returned to his seat, Clarke “felt burning” and began “scratching and adjusting” the area to “fix the problem.”

That failed, because Clarke then said he undid his fly, reached down and “removed his penis from inside of his pants,” according to Christensen. A female in the same row as him noticed and notified a flight attendant.

Clarke wasn’t able to tell his story until two days later, because he bolted from the airport when the plane landed so quickly that he didn’t even pick up his baggage. Clarke had originated from Amsterdam and was heading home to Provo, Utah.

There are some holes in his story. Clarke claimed he applied the peppermint oil before getting on the plane – which would have been around 10 hours before the female passenger spotted his penis.

A search of the bag that Clarke abandoned turned up two boxes containing bottles of “Olbas Oil,” which could have been the pain reliever he was talking about. The search warrant alleges there is probable cause to show the oils will provide evidence of a crime committed on the aircraft.
