Thames Valley Police is releasing an E-fit image as part of an ongoing investigation into a robbery in Milton Keynes.
Between 7.45am and 8am on Tuesday 13 September, a woman was approached by a man on a pathway at the bottom of Marron Lane, Wolverton, near the recreation ground.
As the woman reached the cut-through into the recreation ground, the man asked her for the time, before demanding her purse.
While making this demand, the offender produced a small kitchen knife with an approximately six inch long blade.
The victim gave the offender her purse and he then ran off, possibly down Woburn Avenue back into Wolverton.
Police Staff Investigator Charles Cox, based at Milton Keynes police station, said: “We are now in a position where we can release this E-fit image depicting the man we would like to speak to in connection with this distressing incident.
“Thankfully, the victim was not injured, although naturally, she was very shaken by the ordeal.
“I am re-appealing to anybody who was in the area at around the time of the robbery to contact Thames Valley Police.
“I would be particularly keen to hear from anybody who believes that they recognise the man depicted in this new E-fit image.
“If you do so, or have any information that can assist this investigation, please contact us either by reporting online or by calling 101, quoting reference number 43220411975.
“Alternatively, you can also call the independent charity Crimestoppers anonymously on 0800 555 111.”
