Sorry for the long post in advance.
Just a heads up for all reading but it sounds like he might have been the innocent party in a scam that is currently doing the rounds. In the guys 1st post in the link he mentions it was a low speed crash into the back of a white van and the cause being the person infront of the van stopped for no reason.
A similar situation happened to a friend of mine recently. One of his company vans was on delivery in a built up area doing no more than 20mph. All of a sudden and for no reason the car infront slammed on his brakes causing the van to run into the back of him.
3 guys aged between 18-30 were inside the car. All 3 claimed to have whiplash and all 3 claimed loss of earnings due to whiplash, stress, trauma & nightmares caused by the accident.
They went to one of these no win no fee companies who contacted his insurance company with a claim for 20k for each person!!!
With a little investigation they found out that these guys have been involved in a few accidents already this year and had links to the no win no fee company.
They contacted the insurance with this info but were told that the claim was less than it would cost them to defend the case so they were going to payout. Not too bad for a days work!
This all happened near Hitchin in Hertfordshire.
