A woman was pushed to the ground and had her purse stolen by a man in Bognor Regis.
The robbery happened on Wednesday (May 2) about 12.30pm in the Gravits Lane area whilst the victim was walking alone.
Detective Constable Della Squires, of West Sussex CID, said: “We believe the offender was wearing a distinctive bright yellow t-shirt and hope that the description will jog someone’s memory who may have been in the area at the time.
“I would urge anyone with information to come forward.”
Anyone who can assist police with their enquiries is asked to call Sussex Police on 101, quoting serial 743 of 2 May, or the independent charity Crimestoppers anonymously on 0800 555 111.
