The investigation, launched back in 2015, revealed that three out of five suspected members of the group had worked as couriers. All three have been detained in France. The suspected leader was detained in Klaipėda on Jan. 16. The fifth suspect has been detained in the Lithuanian town of Kaišiadorys.
Four of the suspects are Lithuanian nationals and the fourth is a Belarusian national who has a residence permit in Germany.
Officials said that the suspected leader, a resident of Klaipėda identified by his initials M. B., had not been on the radar of law-enforcement agencies prior to his detention.
The suspects would allegedly transported hashish and cocaine, hidden in cars registered in Lithuania or Germany, from Spain to Norway via France, Germany, Denmark and Sweden.
Two of the Lithuanian couriers were detained in France back in 2015: one with 26 kilograms of hashish and the other with 33 kilograms of the drug. Both men were given prison sentences and fines of 220,000 and 55,000 euros.
The third courier, the Belarusian national, was detained by French officials in June 2016 with 18 kilograms of hashish and 2.2 kilograms of cocaine hidden in his car. He received a prison sentence in France and a fine of 130,000 euros.
A Lithuanian court has issued a three-month arrest warrant for the the group's suspected leader.
