Detectives are appealing for witnesses following a burglary in Fritton, near Long Stratton.
The incident happened late afternoon at about 4.45pm on Friday 30 June 2017 when suspect(s) broke into a property on The Common after forcing a patio door.
Offenders have carried out an untidy search, stealing a quantity of jewellery and keys to two cars.
Suspects have then broken into the garage before stealing a grey Mitsubishi ASX and a Mercedes SKL 250. The Mercedes was later found crashed on Potters Lane in Wattlefield a short time later just after 5pm.
The Mitsubishi also stopped at the scene of the crash and male drivers of both cars were seen to enter an Audi, possibly an A6, which had been travelling in convoy and went off at speed towards Old Buckenham.
This vehicle (Audi) was later found abandoned on the Acle Straight on Saturday morning (1 July 2017).
Officers are keen to hear from anyone who may have witnessed the incident or noticed either vehicle being driven in the area.
Witnesses should contact either Det Con Oliver Pailes or Det Con Jim Starling at Norwich CID on 101 or call Crimestoppers anonymously on 0800 555 111.
