i had this happen to me in tescos car park, there was cctv but they wernt able to show me it due to human rights on the person incase i found out who they were and went after them, didnt go through police as didnt seem worth it when the damage was repaired for £300 and my excess is £500
turned out for the better as my car was out of its MOT when it happened and i didnt know so id have ended up getting done if i did go through the police
