Four suspected Jalisco Nueva Generacion drug cartel members were arrested in the western state of Jalisco by marines, the Mexican Navy Secretariat said Monday.

The suspects, who were detained Sunday in Ciudad Guzman, had firearms, ammunition, security forces uniforms, vehicles and communications equipment in their possession, the secretariat said.

The suspects were identified as Raul Sosa Jimenez, who was allegedly in charge of a cell of the cartel's enforcers, Maria Nelida Flores Reyes, Guillermo Alberto Ramirez Mundo and Jose Antonio Reyes Mundo.

The four are "presumed to be direct associates of Nemesio Oseguera Cervantes, alias 'El Mencho,' who is the leader of the Jalisco Nueva Generacion cartel," the secretariat said.

Unconfirmed media reports over the weekend said Oseguera was arrested in Jalisco two days ago.

At least six suspected Jalisco Nueva Generacion drug cartel members died in a shootout with police in Tonaya, a city in Jalisco, over the weekend.

Cartel enforcers closed at least 22 roads in Jalisco after the shootout, the Federal Police said.

Gunmen used vehicles to block streets across the Guadalajara metropolitan area and in nearby cities, setting 35 vehicles on fire, Jalisco Government Secretary Victor Manuel Gonzalez said.

The Jalisco Nueva Generacion organization was created following the death of Ignacio "Nacho" Coronel, a top Sinaloa drug cartel boss killed by the army in 2010.

Jalisco Nueva Generacion has been fighting Los Zetas, considered Mexico's most violent drug cartel, for control of smuggling routes into the United States. EFE
