SALISBURY — In an incident Saturday morning at Piedmont Correctional Institution, about 36 inmates barricaded themselves into a dorm, said N.C. Department of Public Safety spokesman Brian Haines.

There were no injuries reported.

Much remained unclear about the incident Saturday evening, including how the incident started. Haines said offenders barricaded themselves into a dorm at 11 a.m. He said inmates who instigated the incident were separated into another part of the facility after prison officials made their way in.

Haines said he was not certain about how exactly prison officials made their way in and that an investigation was still ongoing about what offenders were seeking and why they barricaded themselves into the facility.

He said things had calmed down at the prison by Saturday evening.

Piedmont Correctional Institution is an 11-story, medium-security facility housing adult male offenders. It’s located on Camp Road and has an official capacity of 952.
