The shipment was sent from Colombia and was seized in a truck carrying bananas near Warsaw on Saturday.
The drugs were first trafficked to Belgium by sea and then put on a truck driven by a 40-year-old Pole, who has been detained by police.
Apart from its record size, the shipment was also unique for the purity of the drug as it contained 90 percent-proof cocaine. The end product sold on the retail market usually contains 10 to 20 percent of pure cocaine, the police spokesman noted.
The police is now trying to establish whether the drug was to be sold on the Polish market or meant to be transported further.
By comparison, police seized 21 kilograms of cocaine in 2014 and 8 kilograms in 2013. (PAP)
