The incident comes weeks after a prisoner reportedly stabbed two correctional officers at the same facility. 

In that attack on Nov. 8, the two officers "sustained serious but non-life-threatening injuries and were transported to a nearby hospital for treatment," the Baltimore Banner reported, citing the Maryland Department of Public Safety and Correctional Services. 

"Additional responding staff members were also evaluated for minor injuries," a corrections department spokesperson told the website. "The suspect did not receive any serious injuries and is being questioned by investigators."
