A thief laughed at a woman after he snatched her handbag and £200 in cash from the handlebars of her bike.
The woman had withdrawn the money from a cash machine in High Street, Barwell, only moments before the thief, who was also riding a bike, targeted her.
He struck in Barwell Lane after the 24-year-old woman paused for a moment as she emerged from the underpass underneath the A47 at 10am on Wednesday, December 19.
The handbag was found later in a field off Barwell Lane, but the money was missing.
Pc Stuart Clough said: "Fortunately the victim was not injured during the robbery but she was left shaken."
The thief is a white man or youth who was wearing a black hooded jacket with black jogging bottoms and white shoes, which had a distinctive green version of the Nike logo on them.
Anyone with information should contact Pc Clough on 101 or Crimestoppers, which is anonymous, on 0800 555 111.
