OAK PARK HEIGHTS, Minn. — Authorities say they're investigating two separate stabbings that occurred at Oak Park Heights Monday afternoon.

The Minnesota Department of Corrections said the first stabbing happened just after 1 p.m. where two inmates stabbed another inmate, sending that inmate to the hospital. The inmate has since been released and is back at the facility.

The second stabbing happened shortly after the first, in a different part of the building. One inmate stabbed the other.

Authorities say the prison is not on lockdown, but some programming was modified as a result.
