Thirteen more people have been detained by Mexican authorities in connection with the prison escape of drug capo Joaquin 'El Chapo' Guzman.

The federal Prosecutor's Office announced on Friday in a statement that 11 men and two women were arrested and taken to prisons.

Authorities did not release the names of the suspects but said they were detained in connection with Guzman's brazen prison escape.

A federal judge began proceedings against four officials including two intelligence service members and two prison control room employees earlier this month.

All four officials have been accused of aiding Guzman's July escape.

In addition, proceedings were already under way against the control room supervisor and two prison guards.

Guzman escaped from a maximum-security prison in central Mexico on July 11 through a tunnel built right into his cell.

His escape was a humiliating blow to Mexican President Enrique Pena Nieto.

Earlier this month, there were claims that he was spotted in Mexico near the border of Guatemala.

Witnesses say the Sinaloa Cartel leader was taken to a hospital in Tobasco after a car accident, but left before federal authorities could arrive.
