"The joint operation led to the arrest of 26 people", the statement read.
Operation Darkness tracked a group that smuggled huge quantities of hashish — a cannabis-based hallucinogenic drug — from Malaga to Paris and Marseilles.
Investigators found that the group, whose bosses lived in France, wanted to snatch drugs from a rival gang and blame the theft on the guard whom they intended to kill.
The suspects have been charged with participating in a criminal organisation, drug trafficking, auto theft and forgery. A total of 12 pounds of hashish, $832,000 in cash and five luxury cars were seized.
