Police said they are treating the attack in the Castleton Gardens area as a hate crime.
At around 12. 30 am on Sunday, 9 August, the teenager was approached by two men who told his friends to leave.
He was then taken to an alleyway by the men, who stole his phone and bank card, stripped him and then violently assaulted him.
Police said the victim walked to Antrim Road “covered in blood”, before being taken to hospital.
He was treated for grazes and bruises to his face and arms.
