Officials have found three inmates thought to have escaped through a tunnel at a northern Mexico border prison. The number of still-escaped prisoners now stands at 129.
The public safety secretary of the northern border state of Coahuila says three female inmates were found hiding in a prison visiting area.
Jorge Luis Moran told the television network Televisa Tuesday that authorities are searching for inmates who fled the prison in Piedras Negras, a city across the border from Eagle Pass, Texas.
The inmates escaped Monday through a tunnel 21 feet long and 4 feet in diameter, then cut their way through a chain link barrier and escaped onto a neighboring property.
The director and two other employees of the state prison have been detained for an investigation.
