ALLOUEZ, WI (AP)-- Officials say an inmate threw a pot of scalding water in the face of an employee at the Green Bay Correctional Institution.
The Brown County Sheriff's Office says the victim of Monday's attack is a correctional officer.
WLUK-TV reports the employee is being treated at a burn center. A second inmate, who was not the intended target, suffered burns on his back and was treated at the prison.
The Wisconsin Department of Corrections says the prison is on temporary lockdown while the attack is investigated.
The assault comes less than three weeks after an inmate stabbed two employees and injured a third at the prison. The inmate was found dead five days later.
Department of Corrections Secretary Jon Litscher plans to visit the prison soon to meet with staff members.
