(DALLAS) — A prison break has been reported south of the Rio Grande near Texas where 132 inmates escaped through a tunnel.
The escape, according to authorities in Coahuila, took months of planning and preparation to dig a 21-foot tunnel that was 1 feet long and 4 feet in diameter. The inmates then cut through a chain link barrier, escaping to neighboring Northern Mexico.
The prison director and two employees are under investigation as authorities believe that the inmates may have recieved inside help to pull off such an escape.
Federal police units in Mexico along with Mexican troops were deployed to capture the inmates with Coahuila offering up to $15,000 for information leading to an arrest.
