Two businessmen suspected of being straw men for Tomas Yarrington, a former state governor accused of taking bribes from drug cartels, were released by a Mexican court, judicial officials said.

Napoleon Rodriguez de la Garza and Eduardo Rodriguez Berlanga had been arrested in May at the request of the Attorney General's Office for allegedly participating in illegal transactions.

The two men were ordered released from a prison in the western state of Jalisco after federal prosecutors were unable to back up the allegations with evidence, judicial officials told Efe.

The businessmen allegedly laundered money for Yarrington, who served as governor of the northeastern state of Tamaulipas from 1999 to 2004.

The U.S. Justice Department has requested information from Mexico about Yarrington's net worth as part of its investigation into the former governor.

U.S. federal prosecutors on May 22 filed forfeiture cases involving two properties in Texas they allege Yarrington purchased via front men using bribes from drug cartels.

Yarrington has denied having any links to drug traffickers and calims he faces no charges in Mexico or the United States.

The politician, a member of the Institutional Revolutionary Party, or PRI, claims he does not own any real estate in Texas.

Yarrington is not currently the subject of an arrest warrant in Mexico, but his status could change in the future, AG's office spokesmen said. EFE
