speed van

[supergaz]

just wondering if anyone drove towards pyle past margam park this morning and saw the blue van parked up? or have seen it parked up elsewhere?
looked like a normal van, no distinctive marking on the rear but noticed it said police in fairly small writing on the side as i passed.
any ideas if it was a speed van or one of the other types?
i did drive back an hour later hoping to have a good look but it was gone.
anyhow let it serve as a heads up to keep your eyes open for all random parked vans
