An officer at a prison in Jessup suffered a broken jaw and cheekbone during an attack by an inmate, and another officer at the Baltimore City jail was sexually assaulted by a detainee, according to state prison officials.

The first assault occurred Monday at the Maryland Correctional Institution at Jessup. Authorities said the officer was trying to move an inmate from one housing unit to another about 2:20 p.m. when he was hit. It took six to eight other officers using Mace to subdue the inmate, officials said.

On Saturday, prison officials said a correctional officer at the Baltimore City Detention Center reported being sexually assaulted by a detainee. Authorities said an investigation is underway and a person of interest is being questioned. No further details were released.
