Pigeons are historically known for carrying messages. The birds are now being used to carry more dangerous items.

Customs officials in Kuwait nabbed a pigeon this week that had been fitted with a makeshift backpack filled with pills close to the Iraqi border, according to the BBC.

The bird had a total of 178 pills of ketamine, which is often used as a club drug, the BBC reported.

Customs officials said they are aware of pigeons being used to transport drugs, but “this was the first time they had caught a bird in the act,” according to the BBC.
