i would go back to police and get it sorted
and if he trys to sack you then do him for unfare dismisal and trying to keep you from taking the mater any furture you have to much evedance for any legal person to take his side
why he could not of said that it was there fault in the 1st place and thay were sorry and will pay the bills etc to fix your and left it @ that is behond me instead he is trying every trick in the book to cover his guilt
why cant people be honest any more
your boss sounds like a total asshole
