A top Colombian anti-corruption official and a lawyer are facing U.S. money-laundering-conspiracy charges in an alleged foreign bribery scheme, federal authorities said.

Luis Gustavo Moreno Rivera, 35, and Leonardo Luis Pinilla Gomez, 31, were both arrested in Colombia, said acting Miami U.S. Attorney Benjamin Greenberg. Moreno is director of the anti-corruption office for Colombia's chief prosecutor and Pinilla is the attorney.

Moreno and Pinilla sought to obtain thousands of dollars in bribes from a former governor of Colombia's Cordoba region — identified in the document as a confidential source, or CS — who was under a separate corruption investigation, according to a Drug Enforcement Administration affidavit filed in Miami federal court.
