Four Carabineros officers, including the chief of the anti-drug OS-7 unit in Arica and a captain and two sergeants, were arrested with two civilians for allegedly facilitating at least two marijuana shipments from Bolivia into northern Chile.[1] The group was accused of organizing the passage of drug consignments totalling about 1.1 tons of marijuana.[2]

The two shipments had been seized on 5 August and 9 September 2013, and investigators said the officers financed and organized the whole operation.[1] The Arica prosecutor’s office had been investigating the OS-7 unit since October, and its district attorney said the officers were responsible for the trafficking scheme.[2][3]

A day after the arrests, the national Carabineros director reassigned anti-drug chief Colonel Carlos Hidalgo to a missing-persons unit, a move reported as a tough stance on police corruption.[2][3] The Arica prosecutor opened a review of more than 100 cases for possible links between officers and traffickers.[2]
