A 51-year-old woman was the victim of a handbag snatch in Sutton on Sea.
The incident occurred just before 10pm on Friday August 3.
The victim was walking along the main A52 in the village, near the Grove Road junction, when a male on a pedal cycle rode past and grabbed her shoulder bag before cycling off in the direction of Mablethorpe.
The bag is made from black cloth with a grey horizontal stripe on it and contained an amount of cash, paperwork and cosmetics.
The offender was only glimpsed briefly but is described as in his late teens with fair hair and was wearing a dark coloured hoody.
