In a significant operation, Spanish police have successfully dismantled a major methamphetamine distribution network operated by the infamous Mexican Sinaloa cartel. This operation resulted in the seizure of a staggering 1.8 tons of the illegal drug, marking the largest confiscation of methamphetamines ever made in Spain.

The operation, led by Spain's National Police, involved the arrest of five individuals, including the alleged leader of the group, a Mexican national. Alongside the Mexican national, three Spanish individuals and one Romanian were apprehended. The arrests were made during raids conducted at six properties located in the eastern region of Valencia.

According to Officer Antonio Martínez, who spearheaded the investigation, this successful operation signifies the eradication of a dangerous criminal network that was attempting to establish a stronghold in Spain. The group utilized isolated houses in the Valencia region as storage facilities for the smuggled methamphetamine shipments. To conceal their illegal activities, the group ingeniously employed vehicles with false bottoms to transport the drugs to other European countries.

Officer Martínez also shed light on an alarming trend, stating, "We in the National Police thought that the Mexican cartels were not established in Spain. But it is true that due to the pressure they are under in other parts of Europe, above all against their laboratories, we are seeing how they are trying to start operations or set up illegal laboratories in Spain to produce drugs."

This successful operation serves as a significant blow to the Mexican Sinaloa cartel's operations in Europe. The investigation into this major methamphetamine network is ongoing, and authorities have not ruled out the possibility of further arrests.

The Spanish police, in their relentless pursuit to combat drug trafficking and organized crime, continue to demonstrate their commitment to keeping their country safe and thwarting the activities of international criminal networks.
