i don't have any special knowledge in this area, but just thinking about it idly while sitting here, "robbing their homes while they are away" comes to mind as a good proxy.

FYI the source you posted never claimed that John Terry's insurance tried to deny the claim, only mentioning that "some" insurance companies warn of it. However even that claim is questionable, because it isn't even from an insurance company, it's from a content marketing piece by an insurance comparison website.
