A man assaulted during a party in Minneapolis on Saturday has died of his injuries, according to police, who are investigating his death as a homicide.

Officers were called to North Memorial Health Hospital in Robbinsdale around 3 a.m. Saturday after the victim was dropped off at the emergency room with serious head injuries. Police learned from two men with the victim, whose name hasn't been released, that he was at a party in the 2000 block of N. Lowry Avenue in the Jordan neighborhood when a fight broke out and someone punched him in the face, causing him to fall and hit his head, according to a preliminary police report. Neither witness was able to provide a description of the suspect.

Hospital staff later informed officers that the man's brain was swelling and that his condition was critical, the report said. On Tuesday, police spokesman John Elder said the man had died. No arrests were immediately announced.

Officers canvassed the area where the party reportedly took place and found several surveillance cameras nearby, but it wasn't clear if they were working at the time of the incident.

The homicide was the city's 53rd of the year.
