Authorities have released a poster showing the names and photos of 151 men who escaped from a prison south of the border in Nuevo Laredo.
The daring escape took place at the CEDES prison outside Nuevo Laredo in mid-December.
Authorities believe the escaped was masterminded by a Zetas drug cartel leader's nephew at the prison.
Mexican officials filed formal charges against dozens of prison workers for their role in the escape.
Authorities on both sides of the border worked to compile names and photos of the escapees, who are now believed to be working with the Zetas.
The Webb County Sheriff's Office in Laredo released a poster of the escapees in hopes of getting the men back in custody.
It's still not clear which ones of the 151 prisoners are American citizens and which ones are Mexican nationals.
Anyone with information about their whereabouts is asked to contact the Webb County Sheriff's Office at (956) 523-4500.Click here to download a PDF copy of the poster
