Warsaw police have intercepted over 22,000 ecstasy tablets with a street value of over PLN 650,000 (EUR 152,000, USD 172,000), according to reports.
The tablets are believed to have been smuggled to Warsaw from the Netherlands and Germany.
Officers detained three suspects: two Ukrainians, aged 25, and a 22-year-old Pole.
The police had received a tipoff that a parcel sent by courier might contain significant amounts of illegal drugs.
Sylwester Marczak, a spokesman for the Warsaw Police Headquarters, said: “After examining the seized drugs, it turned out that the haul was more than 12,500 ecstasy tablets.”
Marczak added: “Thanks to intensive investigative work, the officers reached another place where a similar parcel, addressed to the same person, was found. The package contained a further shipment of more than 9,000 ecstasy tablets.”
The three suspects could face from three to 15 years in prison.
