Tyres

Hi on saturday night my son Craig who works hard for his money to support himself and his daughter Mila had all 4 tyres slashed by some idiot who just didnt think of the consequences as he didnt realise all 4 tyres had been slashed at the time and gt 2 fixed then drove off not realising the other 2 were going down luckily he realised and pulled over all told it cost him just short of £500 plus a days loss of earnings he as im sure many couldnt just pay this it has now left him severley out of pocket and i just want to try and get at least some back for him i know money is tight for people but anything would be greatly appreciated.
