ATMORE, Ala. — Inmates set a fire, seized control of a dormitory, and stabbed two correctional officials during a violent uprising at a prison in southern Alabama, authorities said Saturday.

The riot prompted the governor to repeat an earlier call for measures to modernize the state’s prisons to make them safer and easier to control.

The William C. Holman Correctional Facility was on lockdown hours after a riot erupted late Friday. Alabama Department of Corrections spokesman Bob Horton said the prison warden and a correctional officer were stabbed at one of the dormitories at the prison, just outside Atmore. Their injuries were not life-threatening.

About 100 inmates were involved, Horton said.

Holman is the only state prison where executions are carried out, although the dormitory where the violence erupted is not death row.

Horton said three emergency response teams were deployed to bring the prison dorm under control. He said the facility is now calm and remains on lockdown.

The violence erupted Friday night when an inmate stabbed an officer while the officer was trying to break up a fight between two inmates. Warden Carter Davenport was stabbed when he and other officers arrived to assess the situation.

Video apparently shot from inside the prison by an inmate with a contraband cellphone shows inmates starting a fire at the end of the dormitory and running around the dormitory.

It was the second violent incident within a week in the state’s troubled prison system, which has come under criticism for overcrowding and staffing level concerns.

A correctional officer was stabbed Monday at St. Clair Correctional facility in Springville while trying to break up a fight between two inmates.

Six inmates were killed across the state prison system in inmate-on-inmate assaults in 2015.

Alabama prisons hold nearly twice the number of inmates the facilities were originally designed to house.

Last month, Governor Robert Bentley announced an initiative to build four prisons, three for men and one for women, to reduce overcrowding and improve safety.

The men’s facilities would be designed to house at least 3,500 inmates. Most of the existing facilities would be closed.
