Latin American members of the activist hacker group Anonymous called off a planned November 5 plan to expose people associated with the Zetas, Mexico's most violent drug cartel, according to the group's blog.

In a post written in Spanish on the group's Latin American blog, the members said they had called off the action after the Zetas met a demand to release a kidnapped group member, and that: "We can say that, while bruised, he is alive and well".

The message left by the dead blogger's body by the notorious Zetas drug cartel.

The hacker group said the person was freed with a note warning that if information were released, the cartel would make the kidnapped member's family suffer, and kill 10 people for each exposed name.

Anonymous members previously threatened by video to release names and addresses of taxi drivers, journalists and police officers who they said acted as "loyal servants" to the cartel to see if that would prompt arrests.
