Just watched a green sedan, reg I think KD04 YFW, pull up in front of a building site across the road. 2 youths jumped out, dressed in "builder-ish" clothes, baseball caps, and with yellow hi-vis gloves on, and tried the doors on the van parked in front of the site. All locked, they started to look into the front yard before a builder appeared and they jumped back in the car and it sped off. Driver didn't exit the car. Was fast and efficient (although in this case unsuccessful).
