As far as I'm aware the collisons unit is made up of civilian staff that do the admin and police staff that investigate the accidents, next time I call I'll ask to speak with an investigator, I dare say I'll get brushed off but if I do I'll take up Chabsy's advice and contact my local counciler. It took 10 days for my statement to be entered onto the collision units books with me chasing them, even now 14 days later it doesn't look like my case has been allocated to an investigator. Thats 2 clear weeks for the scumbag to hide the evidence and concoct an alliby.
