MEXICO CITY – A Mexican official says federal forces have arrested Zetas drug cartel leader Omar Trevino Morales, alias "Z-42."
The official was not authorized to be quoted by name due to government policy.
He says Trevino Morales was arrested in a pre-dawn raid Wednesday in a suburb of the northern city of Monterrey.
The Mexican government had offered a 30-million peso ($2 million) reward for his capture on weapons and organized crime charges.
The suspect is the brother of Miguel Angel Trevino Morales, described as the most bloodthirsty leader of Mexico's most violent cartel.
Miguel Angel was arrested in July 2013, almost a year after marines killed the Zetas' other biggest leader, Heriberto Lazcano "El Lazca."
