The State Revenue Service - Latvia's tax and customs authority - in October detained two Estonian nationals for carrying over 200 kg of hashish, worth more than €2m on the market, the service told the press Thursday.
The two were arrested on the border between Latvia and Lithuania.
Using police dogs, more than 200 kg of hashish were discovered in two cars - a Nissan and a Ford.
The Nissan had a secret compartment at the trunk installed where the drugs were stored while the Ford had drugs stashed in the interior and under the hood.
The drugs amount to 400,000 doses and have a market value of over €2m.
The drug traffickers are currently behind bars.
The Revenue Service also Thursday showcased the use of police dogs to discover drugs.
