It was the staff of these supermarkets located in two Czech towns, Jicin and Rychnov nad Kneznou (north), who alerted the police after finding cocaine bars in the checkouts.

The police said they also searched other places where crates of the same shipment were delivered.

According to public television, the boxes came from Colombia.

"Investigators have seized 840 kg of cocaine so far, in all places they have searched," police said on Twitter.

"At the final distribution, at a price of 3,000 crowns (120 euros) per gram, the dealers would have made more than two billion crowns (81 million euros) from the shipment", according to the same source.
