Mexican military personnel detained four reputed members of the Los Zetas drug cartel, including a suspected accountant for the gang in the northeastern city of Nuevo Laredo, the Navy Secretariat said.

Francisco Dair Montalvo Recio, who acknowledged working as a money man for Los Zetas, was nabbed in a raid Thursday at a home in that border city thanks to intelligence gathering, the secretariat said in a statement.

Also detained at that same residence were suspected Zetas members Ana Maria Cruz Enriquez, Cesar Vazquez Ramirez and Joaquin Samael Ramos Hernandez.

The authorities seized a suitcase with 1.06 million pesos ($81,563) in cash, two handguns, an ammunition clip and 47 plastic bags containing a white powder presumed to be cocaine from the detained individuals, as well as communications gear and computers.

The suspects, weapons, alleged drugs, equipment and money were turned over to federal prosecutors in Mexico City, the statement said.

Los Zetas, a group founded by deserters from a U.S.-trained Mexican special forces unit, started out as the armed wing of the Gulf cartel, but the two criminal organizations had a falling out in 2010 and the Zetas went into the drug business on their own account, gaining control of several lucrative territories.

Even in the violent world of Mexican organized crime, the Zetas stand out for their propensity to dismember the bodies of their victims.

Former Mexican President Felipe Calderon, who handed over power to Enrique Peña Nieto last Saturday, militarized the struggle against the country's heavily armed, well-funded cartels by deploying tens of thousands of soldiers to drug-war hotspots.

Some 60,000 people died in drug-related violence during his six-year tenure. EFE
