Shiiiiit mate, that is horrible =((
I know exactly how u feel, I think we'd all love to get our hands on the bastard who did this, I'd be right a-long side you.
People honestly have no conception, these little ****wits need a serious beating.
I'll certainly be on the lookout for it down in the cannington area when I'm there to visit friends + carousel + cruise etc.
Best of luck with it all mate.
