Perhaps go back to the police with a printout of that and make it very clear to them that Amazon have investigated and concluded that the item was stolen, hence you reporting a theft.

Next step if that doesn't work might be to escalate to your PCC after having contacted your local newspaper to run an article first, ideally with a picture of you looking cross on your doorstep ;)

It is poor form of Amazon to make you jump through hoops if they acknowledge that it is in effect their fault. It is poor form of the police, too, but unfortunately not surprising.
