Police are appealing for witnesses to what they say was an unprovoked attack on a man in a bar in Douglas, which left the victim needing hospital treatment.
The man was punched to the floor in the downstairs area of Fiesta Havana in Wellington Street, just after midnight on Sunday morning.
Police are looking for a man in his 20s, who was wearing a white chequered dress shirt and may have seen what happened.
They also want to speak to anybody else who was in the bar at the time.
The victim of the attack was taken to Noble's, but no information has been released about his injuries.
