"You made a huge mistake by taking one of us. Release him," says a masked, computer-voiced individual in the video.
Reminiscent of a WWE hype video, Anonymous puts forth an ultimatum to Zetas: either release the Anonymous member, or they will release the identities of local police, journalists, taxi drivers and other allies who conspire with the Zetas.
"We cannot defend ourselves with a weapon, but we can do this with their cars, houses, bars, brothels ..." the video message adds, alluding to properties and possessions owned by cartel supporters. "It will not be difficult. We all know who they are and where they are."
Anonymous has given the Zetas cartel until the end of the week to release their kidnapped member.
"If anything happens to him, you will always remember this upcoming Nov. 5," the message states. "Knowledge is free. We are Anonymous. We are legion. We do not forget. Wait and see."
