The Brazilian, not named for legal reasons, is believed to have used two cushion-like implants - attached to a pair of swimming shorts - to hide 1kg worth of cocaine, but his pants plan was foiled at Lisbon Airport in Portugal.

As reported by Sky News, it's not clear how police discovered the fake butt, but officers have said the amount found was the equivalent of 5,000 individual portions of the class A dug.

Later, a different man was taken in by police at a train station, under suspicion of being the one to receive the cocaine.

Although drug possession and use itself is decriminalised in Portugal, drug trafficking could result in present sentences of up to 12 years.
