Witnesses have been urged to come forward in connection with a burglary at a house in Downham last week.
Raiders are believed to have forced their way into the address in the Broomhill area of the town, sometime between last Thursday, November 26, and 2am on Sunday.
It is believed the thieves gained entry to the building through a ground floor window.
A Norfolk Police spokesman said the property was then searched and a set of keys were stolen from inside.
Anyone who saw any suspicious activity in the area during the period stated is asked to contact Det Con Marie Lloyd, of Lynn CID, via the non-emergency 101 number (calls cost 15p).
Witnesses can also contact Crimestoppers anonymously on 0800 555111 with any information.
