4k? thats crazy just for an initial consultation with a lawyer.
Have the police given any sort of indication where they're heading with this? I'd say see what they say on Saturday and then review it.
Fingers crossed they'll drop it and give you a warning and leave it at that. The negative press they can get should be a kick in the backside to these jobsworths.
Good luck and hope it gets sorted out on saturday.
