A contracted security worker is dead and another was taken into custody after a shooting at a Northrop Grumman facility in Anne Arundel County, police said. There were Northrop Grumman employees inside the facility when the shooting occurred, but none were involved in the shooting, Mulcahy said. One of the security workers shot the other, at which point another contracted security worker intervened to prevent further incident and took the person into custody. “This did not involve any Northrop Grumman employees,” Mulcahy said. Charges are pending against the security worker, according to police.
