Prison guards grew suspicious when they saw “four prisoners visibly intoxicated shortly after the pigeon landed on a prison window,” said Josip Pojavnik, deputy warden of Zenica prison.

The pigeon was a pet of one of the inmates. When he and three other prisoners in jail tested positive for heroin, disciplinary proceedings were launched.

It is thought that the drugs were stuffed into tiny bags and attached to the pigeon’s legs.

“We suspect that the pigeon carried the drugs from Tuzla”, a town around 70 kilometres more than 40 miles northeast of Zenica in central Bosnia, added Pojavnik.

The pigeon is now in custody while police investigate who might have loaded it with drugs.
