All inmates were secured around 1 a.m. Friday morning at Lansing Correctional Facility after a riot broke out Thursday afternoon.

Randy Bowman, the Executive Director of Public Affairs with the Kansas Dept. of Corrections, said prisoners in C-Cell House got out of their cells around 3 p.m. and started tearing through property.

He said they are tossing papers, furniture, and laundry; breaking glass; and tearing items off walls.

Bowman said all staff were able to get out of the area without any injuries and the unit has been contained. He said about 20 inmates appear to be involved, while other inmates had returned to their cells.

Tactical teams are monitoring the situation, and will either wait it out or step in if it escalates.

Bowman said some minor incidents occurred in other areas of the prison, but nothing that escalated.

C House is a medium security area.
