A lockdown of the state prison facilities in Sioux Falls has ended.

The lockdown was a proactive security measure, which included searches for dangerous contraband and illicit substances, that began September 15th and was completed October 2nd. It was not a response to an assault, fight, or disturbance – and no staff or inmates were injured.

The Sioux Falls facilities are transitioning off of lockdown status.

The Department of Corrections (DOC) previously released some initial pictures of weapons and contraband seized and will release additional information on the lockdown's success next week.
