On Sunday a burglary took place at a craft centre in the Knobcrook area of Wimborne.
Between 8:45am and 09:30am offenders gained access to Walford Mill Crafts on Stone Lane by smashing a window.
The offenders then stole a large amount of jewellery by smashing the glass cabinet it was in.
Police Constable Dave Hassell, of Wimborne police, asked the public to report anything suspicious around this time.
He added: “I am particularly keen to hear from anyone who has seen or been offered items of jewellery for sale in suspicious circumstances since the time of the incident.”
