Police in Germany say they have seized a large haul of cocaine after smugglers apparently made a mistake that sent the drug to supermarkets.

Workers at five stores in and around Berlin were surprised to find cocaine packed into crates of bananas on Monday — a total of 140 kilograms (309 pounds).

The head of Berlin's anti-drugs squad said Tuesday that the crates had come from Colombia via the German port of Hamburg and the discovery was "pure chance."

German news agency dpa quoted Olaf Schremm as saying that the smugglers had probably made "a logistical mistake."

It's estimated that the drugs would have had a street value of about 6 million euros ($8.2 million).
