Minnesota prison put on lockdown after about 100 inmates refuse to return to their cells

The Minnesota Department of Corrections says an emergency situation at a state prison has been resolved after roughly 100 inmates in one living unit refused to return to their cells Sunday morning. Inmates, however, could remain on lockdown through Tuesday.

Police, firefighters and other emergency teams rushed to the Stillwater prison after it was placed on emergency lockdown at about 8 a.m. local time, the department said. 

The prison is located in the city of Bayport, about 25 miles east of Minneapolis.
