Thanks for the comments on this. My main concern was that the CCTV may not be enough as we don't see the scratch. All other actions may be circumstantial. However, I've heard back from the Police and they are interested and will be paying her a visit. I just want to go tough on her because it's aggressive actions in only 2 days. Would she just key any car parked there or specifically targeted ours? Questions I can't answer.
It would be good if the police do a good initial visit and scare her to settle the damage. I'm not so interested going via insurance as it's an older car and my daily all-rounder. Paint work was good so I am a little pee'd off.
Maybe I'll try to get her mug shot when she opens the door to the police
