José Fernando Aguirre Barreras, known as “El Güero,” an alleged operator with the Cartel de Sinaloa (CDS), was arrested in Mexicali, Baja California, in possession of nine long weapons, narcotics, and tactical equipment. Aguirre Barreras is an alleged member of “Los Rusos,” an armed wing of the Ismael “El Mayo” Zambada faction of the CDS.

Aguirre Barreras was arrested on Monday by officers with the State Security and Investigation Guard (GESI) during an operation in the Miguel Alemán neighborhood. He was detained in possession of nine long arms, magazines, four ballistic vests, 400 grams of meth, and 5.9 kilos of marijuana.

“Los Rusos” is led by José Alexander Sánchez Félix, known as “El Ruso,” who remains at the center of deepening internal friction between “El Mayo” Zambada’s faction of the CDS and those loyal to ”Los Chapitos,” the sons of Joaquín “El Chapo” Guzmán.
