Drug lord 'El Chapo' could be returned to prison he escaped

A Mexican judge has issued an injunction that could send drug lord Joaquín "El Chapo" Guzmán from a prison in a border state back to the maximum security prison from which he previously escaped outside Mexico City, one of his lawyers said late Wednesday.

Lawyer José Refugio Rodríguez said the government could appeal the decision and it could take three months to resolve.

Guzmán was recaptured in January and initially placed back in the Altiplano prison. However, authorities transferred him in May to a federal prison in the northern state of Chihuahua, saying security measures were being improved at Altiplano.

The cartel leader is awaiting extradition to the U.S. and his lawyers complained that the new location made it difficult for them to remain in contact with their client.

Guzmán heads Mexico's powerful Sinaloa cartel. On Tuesday, authorities in Jalisco state announced that his son was among six people abducted from a restaurant in Puerto Vallarta.

Guzmán's lawyers have not spoken with their client since last Thursday, Refugio said. So they had not informed him of his son's abduction, but he could not say whether other relatives had told him.
