Polish border guard discovered over 100 kilograms of cocaine on the seabed of the Baltic Sea, authorities said last week. The drugs were found on the seabed in the area of the Gulf of Gdańsk.

Officers of the Border Guard Maritime Unit located the cocaine on the seabed in the Gulf of Gdańsk, officials said in a news release.

Seven people were arrested in the drug case, with the border guard saying that those detained face from 3 to 20 years in prison if convicted.

The case is of a developmental nature and further arrests in this case are not ruled out.

The border guard said it had “dismantled an organized crime group involved in smuggling significant amounts of drugs.”

Authorities released several images of the operation, whilst a video released by the border guard shows divers finding the alleged drugs on the seabed as well footage of armed officers making multiple arrests at various locations.
