Thames Valley Police is appealing for witnesses after a man was robbed in Milton Keynes on Sunday.
At around 10.30pm, the 59-year-old was walking home from central Stony Stratford through the playground off Vicarage Walk, when he felt a man grab him from behind and put his arm around the front of his neck before threatening him.
The robber stole a wallet and ran off towards the playing fields, leaving the victim uninjured.
PC Ison Wharton, investigating the incident, said: “We believe there were three men involved in the robbery. All three are described as approximately 5ft 9ins, between 18 and 25-years-old and with very dark skin.
“I would like to appeal to anyone in the vicinity of Vicarage Road at the time to contact me.”
PC Wharton can be contacted on 0845 8 505 505. If you don’t want to speak to police or leave your name, call the charity Crimestoppers on 0800 555 111.
