In August 2026, a coordinated security operation involving the Mexican Army, National Guard, and state and municipal police took place at a shopping center in Torreón, Coahuila. The intervention, triggered by reports of an armed convoy, resulted in the detention of 18 individuals, including businessman Ernesto Herrera Reza, also known as ‘El Güino’. Authorities seized firearms and vehicles during the operation. Herrera Reza, who is associated with the dairy producer Chilchota and the company Comercializadora de Productos Lácteos de la Laguna (Coprolac), faces preliminary charges including bribery and violence against law enforcement officers. His arrest is linked to ongoing federal investigations into Segalmex (Seguridad Alimentaria Mexicana).
