Sawt Falasteen - Ex-Gulf Cartel leader released from US prison

Cardenas Guillen was captured in 2003 and extradited four years later to the United States, where he pleaded guilty to drug trafficking, money laundering and extortion.

A Federal Bureau of Prisons official told AFP that Cardenas Guillen, 57, was released Friday and moved into Immigration and Customs Enforcement (ICE) custody.

He has several charges pending in Mexico, but it is not yet known whether the US government will move to deport him.

The Gulf Cartel was once one of Mexico's most fearsome criminal groups, but in recent years lost influence and split into multiple factions.

As leader of the cartel, Cardenas Guillen oversaw a drug trafficking empire responsible for exporting massive quantities of cocaine and marijuana into the United States from Mexico.

Nicknamed "El Mata Amigos" (Friend Killer), he recruited former Mexican special forces soldiers to form his personal guard, which ended up operating on its own under the name of Los Zetas, one ofthe country's most bloodthirsty gangs until its collapse.

After his arrest in the northeast border state of Tamaulipas he was extradited in 2007 to the United States, where he was sentenced in 2010 to 25 years in prison and ordered to pay $50 million.

After his capture, the Zetas began operating more independently until they finally broke with the Gulf Cartel in 2010, unleashing a war for control of its drug trafficking routes in eastern and northeastern Mexico.
