Bit of background, we live in a nice enough road, london suburbs, not huge houses, pitched at young professionals. There's lots of nice cars on the road - Aston Martin, Bentley, a Mercedes wrth about £200k! It's set back from a busy road, so I imagine its quite enticing to thieves.
We've had a few break ins over the last couple of months, they cleaned out a few doors down a couple of months ago, and last week the Aston Martin got stolen.
This morning, the dog barked and went to the window as a plain white transit van was reversing onto our drive (he's quite territorial and will normally bark if a Car/person comes near the house). So I stood by the window watching this van. It remained stationary on our drive for 1-2 minutes then drove off and parked further down the road. After a good few minutes, I saw a man get out with what looked like a toolbag and walk towards a house (I couldn't see what happened then because of the angle)
I don't know if its anything untoward, and it could easily be a workman of some sort. It's just all the pausing (and recent events) which has made me suspicious. If you turn around on someone's drive, surely you don't pause for long, and there was also a long wait before he got out the van.
I've never called 101 before, so don't know if they'd rather you report things like this to be on the safe side, or whether I'm being completely paranoid. What would you do?
