Spain claims its "biggest-ever seizure" of crystal meth, says Mexico's Sinaloa Cartel was trying to sell drugs in Europe

Spanish police said Thursday they had seized 1.8 tons of crystal meth that Mexico's Sinaloa Cartel was trying to sell in Europe, the country's "biggest-ever seizure" of the narcotic.

Police arrested five people during the raid in the eastern Alicante province, one of them a Mexican running the cartel's Spanish operation, a statement said.

"This is the biggest-ever seizure of crystal meth in Spain and the second largest in Europe," Antonio Martinez Duarte, head of the police's drug trafficking and organized crime unit, told reporters.
