Italy: Cannabis farm found in abandoned metro tunnel being used as mushroom farm

Italian police have found a large and flourishing cannabis factory in an abandoned metro tunnel which runs under Rome.

Police raided the tunnel, which is nearly a mile long and was officially being used as a mushroom farm, after detecting the pungent odour of marijuana around its entrance last week.

Italy’s financial police said they had confiscated 340kg of the drug worth an estimated 
€3 million (about £1.9m) – one of their biggest ever cannabis busts. The 57-year-old owner of the farm has been arrested.

The tunnel was built as part of a metro network planned by Mussolini in the 1930s.
