At about 2.30pm on November 29, a man was assaulted in Church Walk and had his mobile phone, wallet, bus pass and bank card stolen.
The victim, a 60-year-old man, was approached by one of the men, who was pretending to be drunk. Two other men approached and barged him to the ground before stealing his wallet and phone.
The suspects fled the scene on foot, allowing the suspect to stand up and walk home.
