A staff member at the Nebraska State Penitentiary in Lincoln was injured Wednesday during an assault by two inmates.
Officials said the inmates used homemade weapons to strike the staff member multiple times.
A chemical spray was used to stop the assault and regain control of the inmates, the officials said. The staff member was taken to a Lincoln hospital for treatment of nonlife-threatening injuries and released later.
Because of the assault, the prison was placed on modified operations. The names of the staff member and inmates will not be released, officials said.
