A violent thug left a 22-year-old man needing hospital treatment after a hate incident in Kersland Street in the West End.
Detectives are appealing for information about the incident on Wednesday August 9.
Two men were on Kersland Street near to Great Western Road at around 2.00am when one of them was subjected to homophobic abuse by a stranger.
When the victim’s friend tried to intervene, the man assaulted him, leaving him with a serious facial injury.
The 22-year-old man was taken to the Queen Elizabeth University Hospital and released after treatment.
The suspect is described as white and in his early 20s.
He was wearing a black top and black tracksuit bottoms.
He was also in the company of a woman described as being in her early 20s, 5ft6 and with shoulder length blonde hair.
The pair were last seen walking east along Great Western Road.
Detective Constable Stuart McDonald from Drumchapel CID said it was vital the attacker was caught.
He said: “This despicable individual not only subjected an innocent man to homophobic abuse, but also assaulted his friend when he came to his aid.
“This type of behaviour is absolutely unacceptable and I would appeal to anyone who either witnessed the incident, or saw the man and woman described above, to please get in touch.”
Anyone with information is asked to contact officers at Drumchapel CID via 101 and quote incident number 0268 of Wednesday August 9.
