Same here in Essex - dark, dank and miserable. Just been chatting to PC Plod at the front door. On Sunday, around 12.15 at night - I just looked out of my bedroom window before going to bed and saw a white transit van pull up across the road - a lad got out and walked up my road. I swopped windows (neighbourhood watch, you understand) and saw the lad coming back down the road carrying something in his hand.
The white transit van was waiting for him - when I focused my eyes,I realised he was carrying my neighbour across the road's plant pots - he then broke into a run, got back into the van and disappeared.
