Lunty I feel your pain mate & hope these scumbags trip up & get caught, jailed & left to rot. This is the first I'm hearing about it, I don't read the papers or watch main stream news. As much of a pain in the butt as it can be sometimes, offsite secure storage (insured) is the way to go, You'll be able to sleep a lot better, I know I do since doing so.
I hope your PM's are returned, the police do their job, the courts do their job & your life can be put back on track with the lease amount of stress on you your family mate.
