RABAT, Feb. 12 (Xinhua) -- Moroccan security services have seized over 3.25 tons of cannabis at the Tangier-Med Port and arrested one person, Moroccan police said in a statement on Monday.

Police officers and customs personnel found the drugs, which were in the form of compressed resin, hidden inside the trailer of a truck transporting a shipment of fish heading toward Spain.

The driver, a 32-year-old Moroccan man, was arrested and placed under investigative custody to determine all the possible links with local and international drug-trafficking networks, it said.

Despite efforts in the past decade to crack down on cannabis farming, Morocco remains one of the world's largest producers of cannabis resin.
