It came after a 68-year-old man suffered what were described as serious facial injuries in an assault at around 5.30pm on Saturday.
A spokesman for the force said at the weekend: "The 37-year-old man who police are looking for is known to the victim – he is described as being 5ft 10in with a slim build and gaunt appearance. He has mousy-colour hair that has been dreadlocked and an ‘unkempt’ ginger beard.
"He also has a colourful sleeve tattoo on his left forearm. He is believed to be wearing a white checked shirt, beige or green trousers, and boots."
Residents were told to lock their doors and windows and were urged to contact police immediately if they saw the suspect.
