About 400 inmates refused to leave the recreation yard Monday night, officials said. Roughly two dozen inmates threw rocks, broke glass and tried to destroy property before they were brought under control about 3 1/2 hours later, said Corrections Corp. of America spokesperson Louise Grant.
Facility spokeswoman Rose Thompson said that fires were started in some dorms.
Two employees at the Mineral Wells Pre-Parole Transfer Facility were treated on site for minor injuries during the disturbance, said Grant. There were no reports of injuries to inmates.
Officials were investigating what caused the problem at the facility, about 40 miles west of Fort Worth. Those who are found to be instigators will be transferred to other facilities, and they could face charges.
The all-male, minimum-security facility has 2,100 beds and houses inmates from the Texas Department of Criminal Justice, according to Corrections Corp.'s Web site.
