The mugging took place at about 2:30 a.m. when two or three men tried to rob another man on Hamilton Street, near Hawthorne Park, less than a mile from Rutgers, according to an alert from the university police.

The victim, who was not affiliated with the University, was stabbed with some sort of sharp object during a fight, the alert said.

The man was treated by first responders at the scene between Woodbridge and Bridge streets, but died from his injuries, according to police.

No further details of the incident were made available.

New Brunswick Police Capt. J.T. Miller referred all questions to officials at the Middlesex County Prosecutor's Office, who did not immediately respond to emails.

City police are also looking into a shooting that happened at about 1:20 a.m. on Spring Street near the Middlesex County Superior Court house, authorities said.

The two men were treated at a local hospital for non-life threatening gunshot wounds to the leg, but have been uncooperative with detectives investigating the incident, Miller said.
