A 20 carat gold ruby necklace and a Gucci watch have been stolen during a burglary in Roydon, police say.
Detectives have appealed for witnesses to come forward about the break-in, which is believed to have happened sometime between 9.30am last Friday, July 10, and 3pm on Monday.
The raiders are thought to have forced their way into the property through a rear patio door.
Detectives say they want to hear from anyone who may have seen any suspicious activity or vehicles in the Roydon area during that period.
Anyone with information is asked to contact Det Con Alex Heathcote, of Lynn CID, on 101.
