Sorry to hear this... i got burgled a few months back.. while i was upstairs sleeping they came into my house looking for my car keys.... didnt find them so took anything they could from downstairs.. which amounted to a over a couple of thousand pounds.
I phoned the police and they were around in under 30mins, knocked on the neighbours doors, took my statement, finger prints.... and had lots of updates from them - almost weekly + they came around and fitted new locks + battery powered shock sensors. I was very impressed with the service i received from Derby Constabulary!
In terms of insurance i didnt have proof (boxes, receipts or manuals) for a lot of my items (3year old laptop + camera's) but i gave them a description and my insurance company (Direct Line) were very handy and sorted me out quickly.. well they would have if their loss adjuster (everest) were not arses and wasted my time writing letters instead of calling while i was away on business.
