A trio of dope sellers in the Lomas de Zamora district of Buenos Aires allegedly tied up to 13 grams of pot around their winged messengers’ necks to make around 20 deliveries a day.

Cops rumbled the small-time ring’s ruse after stumbling across a lost white dove carrying a small package packed with illegal substances.

“It was released and we were able to follow it,” a police spokesman told ABC. “Then it was a question of waiting and following again.”

The three men, who trained the birds to fly the marijuana from their makeshift farm to the distributors’ depot, were arrested.

Cops said that the distance between the two buildings was short, so the birds could transport “substantial amounts” every day.

“We talked to pigeon trainers and they told us that these pigeons were capable of making up to 20 trips per day,” police chief Nesto Larrauri said.

“With pigeons they could ship their drugs without taking any risks,” he added.
