The Stillwater state prison will remain on lockdown until at least Tuesday after about 100 inmates refused to return to their cells for about seven hours on Sunday.
Officials from the Minnesota Department of Corrections (DOC) said the situation has been "resolved without incident" and no one was hurt. The Bayport facility was placed on lockdown at around 8 a.m. Sunday as prisoners protested problems stemming from staff shortages.
DOC spokesman Andy Skoogman said the situation was "calm, peaceful and stable" throughout the day. The facility remained on lockdown status after nearly all prisoners returned to their cells around 3 p.m. Sunday.
Reports were mixed regarding what triggered the protest within the prison.
Skoogman said some of the incarcerated men in the unit were dissatisfied because cell release schedules were modified over the Labor Day holiday weekend, meaning prisoners had less time than usual for showers, phone use and recreation.
The DOC said schedules had to be modified due to "staffing challenges."
On Sunday morning, about 225 men from one housing unit were released from their cells to shower, call their relatives and socialize, but about 100 refused to return to their cells around 8 a.m. Skoogman said DOC staff were quickly removed from the common areas of the housing unit while two correctional officers stayed in the unit's secure control area. The two officers in the secure control area were in constant communication with facility command personnel during the incident, he said.
The protesting prisoners were calm, talking with each other and playing cards, Minnesota Corrections Commissioner Paul Schnell said during a news conference Sunday afternoon. "There was never any type of violence throughout the incident," Schnell said.
