Witnesses are being sought after a man was robbed in Narborough last week.
The incident happened on Wednesday at about 9.15pm when the victim, a man in his 30s, was walking his dog near Chalk Lane.
He was approached by four men, and one of them pulled out a knife and demanded his wallet. A second man then searched his jacket and stole cash, a mobile phone and some jewellery.
The victim received a minor injury to his neck.
Anyone with information should contact Det Con Ellie Knul at Thetford CID on 101 or Crimestoppers anonymously on 0800 555 111.
