PIEDRAS NEGRAS, Mexico (AP) — More than 130 inmates escaped through a tunnel from a prison in northern Mexico on Monday, setting off a massive search by police and soldiers in an area close to the U.S. border.

Authorities in Coahuila state said the 132 inmates fled the prison in Piedras Negras, a city across the border from Eagle Pass, Texas, through a tunnel that was 21 feet long and 4 feet in diameter, then cut their way through a chain link barrier and escaped onto a neighboring property.

Coahuila Attorney General Homero Ramos Gloria said the director and two other employees of the state prison have been detained for an investigation into the escape and are being questioned about possible involvement by authorities at the penitentiary. The prison houses about 730 inmates and the escape represented almost a fifth of its population.
