Police at Charles de Gaulle airport in Paris have seized 1.3 tonnes of pure cocaine on an Air France flight from Venezuela.
The BBC reports the drugs were found packed inside 30 suitcases on 11 September.
Interior minister Manuel Valls said on Saturday it was the biggest drug haul ever made in the Paris area.
He said six people were arrested. They are accused of being members of an international drug smuggling ring.
Officials believe the drugs were meant for sale in France and had a street value of 200 million euros ($US270 million).
The Air France flight came from Caracas. The suitcases with the cocaine reportedly were not registered to any passengers.
