A yob punched and robbed a terrified woman while she waiting for a taxi in Sheffield.
The incident happened when the 21-year-old victim was walking along Crookesmoor Road, towards Conduit Road, in Crookesmoor at 1am on Sunday, September 24.
While she waited at the side of the road for a taxi, an unknown man is reported to have walked past her but then returned and pushed her up against a wall.
He began threatening her and demanded she hand over her handbag.
A South Yorkshire Police spokesperson said: "The man is then understood to have searched the woman’s handbag, before demanding her mobile phone and punching her in the face, causing her to fall to the floor.
"He then searched the victim’s pockets while she was on the floor, threatening further violence before assaulting her again.
"The victim is believed to have fallen unconscious and when she awoke, the man was gone."
Detectives are hunting the perpetrator and are now appealing for witnesses to come forward.
PC Donna Simcock said: “This was an extremely nasty and unprovoked attack on a woman who was simply waiting for a taxi.
“We’re really keen to hear from anyone who may have witnessed the robbery on Conduit Road on that Sunday morning, or anyone who may have seen someone matching the description of the suspect.
“Thankfully the victim was not seriously injured, but it is important we identify the person responsible for this awful robbery.”
