In reply to James Malloch:
As an update, Police responded saying they won’t use the information unless one of the vehicle owners get in touch.
I didn’t get in touch with the van company (been busy) but I did get a call from someone today who saw my note. They said they had CCTV of the incident, and that the car had been parked in the same place (right next to my big, bold sign) for the last 2 days.
They were going to move the sign and his own number onto the windscreen to see if they wanted to get in touch. So I’ll leave it up to the driver now.
The guy who called has had two cars written off by lorries on the same street and had to rely on his CCTV to find out who did it. Sounds like a common occurrence.
