Mexico crackdown on Sinaloa Cartel Mayiza faction

In early July 2026, state security forces in Mexicali seized two properties tied to the La Mayiza wing of the Sinaloa Cartel, arresting former municipal officer Juan Israel “N” and confiscating weapons, vests and psychotropic substances. Later that month, a joint operation by the Secretariat of Security, the Navy and federal prosecutors captured Fernando “Cebollo”, a senior La Mayiza operative, in Manzanillo, Colima, finding meth‑amphetamine, a long gun, a pistol, a revolver and ammunition.

On 27 July, Mexico widened the campaign, detaining additional high‑profile criminals across several states. In Guanajuato and Michoacán, Carlos Giovanni “El Ojón”, a Jalisco New Generation cartel leader, was seized along with weapons and drugs. In Colima, authorities again arrested Fernando “Cebollo”, confirming his role in the Mayiza faction and seizing further meth‑amphetamine and firearms. The crackdown also netted a suspected Los Chapitos leader (“El Tío”) and an alleged homicides suspect, E.T.L. “El Tello”, in Oaxaca. In Tijuana, the state prosecutor linked Juan “N” to a failed homicide and placed him in detention after a prolonged investigation. These coordinated multi‑agency actions illustrate Mexico’s intensified, intelligence‑driven strategy to dismantle the Mayiza wing while simultaneously striking other major cartel networks.
