132 inmates escape Mexican prison on U.S. border

CNN reports Mexican authorities have detained a prison director and two other prison officials after 132 inmates escaped from the facility Monday, officials said.

The attorney general for Coahuila state had asked a judge to detain the three prison leaders for 30 days while an investigation into the escape from the border city of Piedras Negras began.

Piedras Negras is across the border from Eagle Pass, Texas, and about 150 miles from San Antonio.

The inmates escaped one by one from what's known as a social rehabilitation center, a minimum-security facility, by using a 7-foot-long tunnel, according to a statement from the state attorney general. The escapees then cut through a chain-link fence and ran through an empty lot.

The tunnel, which was about 4 feet wide and nearly 10 feet deep, began inside a wood shop inside in the prison, authorities said.
