WILLIAMSBURG COUNTY, SC (WCSC) - Authorities say three inmates escaped from a federal prison in Williamsburg County and returned a couple of hours later.
The US Department of Justice says the incident happened at the Federal Correctional Institution on Highway 521 outside of Salters.
According to officials, at 6:30 p.m. on Saturday, the inmates were discovered missing during an impromptu count.
"However, each inmate returned back to the Satellite Prison Camp at 8:00 p.m. the same evening," government officials said.
Authorities say local law enforcement was immediately notified upon the discovery and an internal investigation was initiated.
A report states the satellite prison camp is a 128 bed, minimum security facility which houses non-violent offenders and is not enclosed by a fence.
