Customs inspectors discovered over 300kg of cocaine while inspecting a container supposedly containing cans of pineapple at Malta Freeport. The haul was described as the biggest ever by the Customs Department.

The container ship, which stopped in Malta on its way from Ecuador to Spain, was flagged as a potential high risk following risk analysis performed by the Customs Department.

Upon inspection, Customs officials uncovered six large sacks containing several hold-all bags with over 300kg of a white substance which turned out to be cocaine.

"It is estimated that the haul has a street value of tens of millions of euro, however, such value which is to be confirmed following a purity analysis is accurate weighing," Customs said.

A magisterial inquiry is under way and the police are investigating.

Informed sources said that the haul is worth some €20m, with one gram being worth some €70.

The Customs Department said a purity analysis is underway.
