A Minnesota prison was placed on emergency lockdown on Sunday after about 100 prisoners refused to return to their cells, authorities say.
The Minnesota Correctional Facility – Stillwater houses roughly 1,200 inmates, and around 100 inmates participated in the group protest. A spokesperson told the Associated Press that the reason for the prisoners' refusals "remains unclear."
The Minnesota Department of Corrections told FOX 9 Minneapolis that the prison's staff members were removed from common areas. A Special Operations Response Team was also deployed to handle the crisis.
Two prison officers were in a secure control area as of Sunday afternoon, and have been in contact with authorities.
