Thames Valley Police is appealing for witnesses after a woman was robbed of a gold ring in Milton Keynes.
The incident occurred at the junction of Colliers Wood and Goldhawk Road in Monkson Park, part of Ouzel Valley Park, at approximately 11.10am on Monday (7/6).
The victim, a woman aged in her thirties, was approached by a man, and following a brief discussion, the offender took out a flick knife and asked the victim to hand over her gold ring.
The victim took the ring off and handed it to the offender, who then left in the direction of Woughton on the Green.
The offender is described as a black man, approximately 20-years-old.
He was around 5ft 7ins to 5ft 8ins tall with a very slim build.
He had short curly hair, with the top part of his hair shaved into a rectangular shape.
He had a bony face with prominent cheek bones, but was wearing a black face mask.
The stolen ring is thin white gold with a large light green stone with five small diamonds on either side of the main stone.
The victim was not injured in the robbery.
Investigating officer Detective Constable Sebastian Kuzoe, of the Priority Crime Team based at Milton Keynes, said: “This was a frightening ordeal for the victim.
