Marines arrested two men in this capital in possession of illegal drugs and weapons, the Mexican government said.

The marines were on patrol in the Colonia Hipodromo Condesa area when a citizen approached them with a tip about the presence of armed men in one of the residences, the navy department and interior ministry said in a joint statement.

When they went to the residence, the marines saw an armed man standing outside, who entered the home on spotting the naval personnel.

The marines followed the subject inside, where they found him and another man in possession of a military combat rifle and 50 small bags of what appeared to be marijuana.

The navy personnel took Francisco Javier Valles Zuñiga and Erick Coria Urbina into custody without firing a shot, according to the official statement.

Mexico's armed forces assumed a central role in the battle against drug trafficking during the 2006-2012 administration of President Felipe Calderon. EFE
