MEXICO CITY (Reuters) - Mexico released on Tuesday Abraham Oseguera, the brother of Mexican drug lord Nemesio "El Mencho" Oseguera Cervantes of the powerful Jalisco New Generation Cartel (CJNG), the security ministry said.

Oseguera, also known as "Don Rodo", was detained on April 21 by army soldiers working with the National Guard police in Autlan de Navarro, Jalisco, in what officials touted as a major blow to organized crime.

CJNG is widely viewed as the most powerful gang in Mexico alongside the Sinaloa Cartel, as both fight over lucrative smuggling routes into the United States as well as many other criminal rackets.
