Kosovar police say they have arrested two men after discovering counterfeit currency valued at more than 2 million euros in the trunk of a car crossing into the Balkan nation from Albania.

The counterfeit bills with a face value of 2.1 million euros ($2.2 million) were found early on March 10 in a bag in the trunk of the car driven by an Albanian citizen, a police statement said.

Both the driver and the passenger, a citizen of Cameroon, were subsequently taken into custody.

Police said it was the largest confiscation of counterfeit currency since the end of the 1998-99 war in Kosovo, which declared independence from Serbia in 2008.

The car also contained materials capable of being used for counterfeiting, a French resident permit, and two Cameroonian passports, police said.

Kosovo is seeking to join the European Union, which says corruption remains a “serious problem” for the Balkan country.
