Another Bolivian cop arrested on drug suspicion

Bolivian authorities say they've arrested a recently retired police colonel on suspicion of drug trafficking, the second senior Bolivian official snared for alleged cocaine trafficking in less than a month.

Prosecutor Luzgarde Alcantara says Col. Robert Miguel Valdez was arrested outside the eastern city of Santa Cruz Wednesday after agents found traces of cocaine in his vehicle.

Valdez was Interpol chief in Santa Cruz until December.

President Evo Morales said Thursday the arrest follows his order to purge the police of anyone corrupted by drug trafficking.

Last month, a recent director of Bolivia's counternarcotics police was arrested in Panama and deported to the United States to stand trial on cocaine trafficking charges.
