Mexican authorities have captured the son of the alleged leader of the country's most violent cartel in the western state of Jalisco.

A federal official speaking anonymously because he was not authorized to discuss the arrest confirmed that federal forces captured Ruben Oseguera Gonzalez, alias "el Menchito," early Tuesday. His father is Nemesio Oseguera Cervantes, leader of the Jalisco New Generation cartel.

It is at least the second time the younger Oseguera Gonzalez has been captured. Federal forces arrested him in January 2014.

The gang is blamed for an ambush that killed 15 state police officers in April and for a May 1 attack in which a rocket launcher shot down an army helicopter, killing 10. Federal forces last month killed 42 suspects on a ranch in Michoacan state.
