The incident took place on Friday night, June 26, when the three victims were attacked by a group of three men, one armed with an iron bar, in the Whitewell Road area.
Alliance Councillor Nuala McAllister said: “This was a disturbing incident and I must condemn it. It is very disappointing to hear of attacks like these in North Belfast.
“My thoughts are with the victims as they recover from their ordeal and I would appeal for anyone with information to contact the PSNI as soon as possible.”
