A disabled man was assaulted in Tenth Avenue by three teenagers who have targeted him before on Sunday.
The 29-year-old was walking into Third Avenue at about 4pm when the teens approached him and pulled his shopping bag from his grasp.
They pushed him, verbally abused him and threw his shopping around the street.
PC Jag Dhillon said: “The victim in this case is vulnerable and has experienced this type of abuse before by the same group of people. We need to stop this behaviour now and I would urge anyone who witnessed the incident in Sunday or anyone who can help identify those responsible to contact the police.”
The first offender is described as a mixed race boy with short dark hair and a skinny build, wearing tracksuit bottoms and a hooded top.
The second offender is described as a white boy with short hair and light coloured eyes, wearing a grey jumper or hooded top.
The third offender is described as a white girl with brown shoulder length hair and blue eyes, wearing a shirt.
