Police in Italy said it had busted a large drug trafficking network that use buses to bring marijuana from Albania to Germany and other countries.

According to investigators in Rome on Tuesday, security forces had detained 55 suspects in three countries.

The suspects include 52 men and three women reportedly to be of Albanian, Nigerian, Italian and Gambian nationalities.

The suspects were said to have brought illegal drugs from the southern Albanian city of Vlora to Italy, where they were repackaged and distributed using buses and trains, according to the Carabinieri forces.

The Italian capital is the hub of several, cooperating gangs.

The police said one couple was detained in Germany.

Italian authorities closely collaborated with authorities in Germany and Albania, based on investigations from 2018 and 2019, which at the time also led to dozens of arrests, the Carabinieri said.
