Mexican authorities announced the arrest of another 11 suspected members of the Los Zetas drug cartel in the violence-plagued northeastern state of Nuevo Leon.

They were detained a few hours prior to the capture of 18 purported Zetas enforcers in that state after a gun battle.

The Nuevo Leon Attorney General’s Office paraded the group of 11 detainees - a cell of five women and six men accused of kidnappings and homicides - before the media on Friday, a day after they were arrested in the city of San Nicolas de los Garza while attempting to collect a ransom.

Among the detainees was 25-year-old Jaime Cabrera Escalante, suspected Zetas chief in San Nicolas, part of the metropolitan area of Monterrey, the state capital.
