A crossbow and two air guns were stolen during a burglary in Feltwell on Tuesday.
Raiders smashed a rear patio door to gain entry to the address in Long Lane between 10.15am and 9pm.
As well as the weaponry, they also stole a quantity of jewellery. Two pillow cases, which were taken from a bedroom, may have been used to carry the stolen property, police believe.
Any witnesses are asked to contact PC Nicky Gaughan of Thetford police on 101 (calls 15p).
