At about 3.45am police received a report that two men had got into an altercation with a 42-year-old woman on Holmeside in the city centre.
Her 32-year-old male partner then intervened and entered into a verbal altercation with the two men.
He has then been assaulted and taken to hospital with what is believed to be a single stab wound. He remains in hospital in stable condition and his injuries are not believed to be life-threatening.
Three male suspects – aged 31, 24 and 20 – were located a short time later and arrested on suspicion of assault.
They remain in custody at this time.
Police enquiries lead them to believe that two men had exited a nearby pub and started being verbally abusive to the victim’s partner with no provocation.
