LOWER MANHATTAN — A security guard for a New York University dormitory building stabbed his supervisor during a dispute in Lower Manhattan early Saturday morning, police said.

Officers were called to the Broome Street Residential College building around 1 a.m., according to the NYPD.

A 38-year-old security guard got into an argument with his 45-year-old supervisor and the fight turned physical, police said.

The guard then pulled out a weapon and stabbed the supervisor in the neck, torso and shoulder, police said.

The victim was taken to a hospital in stable condition.

The guard, who was not immediately identified, fled the scene and remained on the loose, police said.

NYU spokesman John Beckman said the dorm was not occupied by students and the university’s guards are not allowed to carry weapons.

“The university is shocked by this unprecedented incident and deeply concerned for the welfare of the injured public safety sergeant. NYU is a safe campus, our public safety officers do an exemplary job safeguarding our community, and this kind of act is both unheard of and utterly out of character with the role our public safety officers play on campus,” Beckman said.

NYU issued a university-wide alert banning the guard from all facilities and suspended him pending termination.

“The university is cooperating with law enforcement efforts to apprehend the assailant as quickly as possible and to investigate the circumstances of the stabbing,” Beckman said. “Our thoughts and concerns are with the brave, injured sergeant and his family, and we pray for his health and swift recovery.”
