CCTV images of the offender, who was wearing a distinctive jacket, have been released following the robbery in Park Square on Monday April 25 at around 8.25pm.
The woman was approached from behind and pushed over, before the male suspect ran off past Pizza Express towards St Paul’s Street.
The man was described as olive skinned, possibly eastern European, and aged 25 to 30.
Detective Constable Simon Daley, of West Yorkshire Police, said: “We have conducted an extensive trawl of CCTV cameras in the area and although we have no viable images of his face, he does appear to be wearing a distinctive black jacket with a blue and white striped patch on each shoulder.
“We believe the suspect went to the Beeston area after the offence and we would like to hear from anyone who knows someone who wears a jacket like that, fits the general description and has links to Beeston.
“We would also like to hear from anyone who witnessed the incident or who saw the man in the area around the time.”
Anyone with information is asked to call police on 101, quoting crime number 13160177191, or the independent charity Crimestoppers anonymously on 0800 555111.
