Peru's police chief says agents have arrested a top Colombian drug trafficker and gangster who entered Peru in late January with a false passport.

Gen. Raul Salazar says Jacinto Nicolas Fuentes German, alias Don Leo, was arrested Wednesday in the affluent seaside Lima district of Miraflores with the help of Colombian police.

Salazar identified Fuentes as head of the Urabenos criminal gang in Colombia's Bajo Cauca region, which is a traditional stronghold of far-right paramilitaries.

After the illegal Colombian militias disbanded in the middle of the last decade, many of their members formed drug-trafficking bands of which the Urabenos is among the most prominent. Urabenos has battled other criminal gangs for control of drug trafficking routes out of Colombia, which is the top exporter of U.S.-bound cocaine.
