Women have been robbed of shoes and coats in a series of incidents.
The latest was on February 10, when a woman was targeted at 11pm in Woodstock Road. She was pushed against a fence before her attacker wrenched the shoes from her feet and fled.
The man is described as of average build, about 5ft 10in tall, and aged 20-35. There have been two similar offences, in which lone women have had their coats grabbed.
