Hiya, My wife's colleague left his imac at my house without my knowledge and while he was gone, my house was broken into. His computer was still in its box and the thieves basically walked in through my unlocked front door and took it. Am I liable and have to replace it? I don't want to claim on my home and contents insurance for obvious reasons but I feel a bit hard done by. If I do have to pay then so be it. He knew about our lack of security in the house.
