The Lincoln Correctional Center is on lockdown after inmates assaulted nine staff members earlier this evening.
The Nebraska Department of Corrections had previously said six staff members were assaulted.
The Department said the inmates were refusing to return to their housing units when they lashed out on the staff members.
In a news release, the Department of Corrections also said there is no risk to the public and the immediate priority was to get medical care for the staff members. Lincoln television station KLKN is reporting that all nine staff members were treated and released.
