A Canadian man has been sentenced to six months in U.S. federal prison for groping an American Airlines flight attendant, AP reported.

Enio Socorro Zayas, 50, was sentenced Monday in Miami federal court, according to court records. He pleaded guilty to assault in October.

According to a criminal complaint, Zayas was traveling on an American Airlines flight from Cancun, Mexico, to Miami International Airport in August when a flight attendant serving refreshments left snacks on Zayas’ lap because she believed he was asleep. Zayas then reached around his side, intentionally grabbed the woman on the back of the leg and moved his hand up to her buttocks, all without the flight attendant’s consent, investigators said.

When she turned away, the flight attendant "felt a hand grip the bottom of her thigh and move upwards towards the lower portion of her buttocks before rubbing firmly from side to side," the affidavit reads, CNN reported.

One of the passengers on board corroborated details of the incident to law enforcement, according to the affidavit.
