Mexico drops drug link charges against General Angeles
Prosecutors in Mexico say they have dropped the charges against retired general Tomas Angeles Dauahare.
Gen Angeles, a former deputy defence minister, had been accused of having links with a drug cartel.
Prosecutors said they could not corroborate allegations made by two witnesses against the general.
Shortly after the announcement, Gen Angeles was released from the maximum-security jail where he had been awaiting trial.
He had been facing charges of "organised crime to further drug-trafficking", which he had denied all along.
Two people in a witness protection programme, known under the code names of Jennifer and Mateo, had accused him of links with the Beltran Leyva cartel.
They said Gen Angeles was tipping off cartel members about police and army operations against them in exchange for money,
Prosecutors said that they had found no convincing evidence "corroborating the testimony of the protected witnesses and no proof whatsoever which would confirm the allegations made by Jennifer and Mateo".
Jennifer was the same witness who had also accused the former anti-drugs tsar Noe Ramirez Mandujano of links with the Beltran Leyva cartel.
Mr Ramirez was cleared of the charges on Monday and released earlier on Wednesday after more than four years in prison.
The judge in that case asked for Jennifer to be investigated on suspicion of giving false testimony.
Both Mr Ramirez and Gen Angeles were investigated as part of Operation Clean-up, an attempt by former president Felipe Calderon to eradicate corruption within the Mexican security forces.
Felipe Calderon brought in the army to fight drug cartels when he took office in 2006 and promised to be tough on any officers who were found to accept bribes by drug gangs.
But critics say drug gangs would falsely accuse officers to get rid of those who stood in their way.
