Mexico’s military has captured a senior leader of the powerful Jalisco New Generation Cartel (CJNG), marking another significant setback for the criminal group just two months after its top boss was killed.

Authorities said Audias Flores Silva, also known as “El Jardinero,” was arrested while hiding in a roadside ditch near El Mirador in the northwestern state of Nayarit. No casualties were reported during the operation.

Flores Silva was considered a potential successor to cartel leader Nemesio Oseguera Cervantes, alias “El Mencho,” who was killed in a major military operation in February. His death triggered a surge in cartel violence, including attacks on businesses, vehicle burnings and road blockades that left more than 70 people dead.

Mexican officials said Flores Silva previously served as head of security for Oseguera Cervantes and played a key role in overseeing drug production and trafficking across several states, including Nayarit, Jalisco, Mexico State and Zacatecas.

The United States had offered a $5 million reward for information leading to his arrest and has sought his extradition since 2021 on drug conspiracy and firearms charges.

US Ambassador to Mexico Ronald Johnson welcomed the arrest, calling it an “important step” in tackling criminal networks involved in fentanyl trafficking.

Security analyst David Saucedo described the capture as a “significant blow” to the cartel’s leadership, though he cautioned that such groups often adapt quickly and continue operations despite leadership losses.

The CJNG remains one of the most powerful criminal organisations in the region, with operations spanning much of Mexico and extending to around 100 countries, including the United States.
