Can you help find out who did this

My car (red Toyota Aygo) was parked in the park & ride car park next to Aberdare Railway station all day on Friday 11th August from 7:30 am. I caught the train to Pontypridd for work and when I returned at 5:45 pm, the back windscreen had been smashed. A rock has been used by the looks of it, as I found it lying behind the passenger seat. I have reported it to the Police but they haven’t done much other than said they will view the CCTV in 5-7 days. I have contacted the insurance company too.

I’m just wondering if anyone saw anything and if so, could you please let me know any info via private message so that I can pass it on to the police. This is criminal damage and the person or persons responsible should not be allowed to get away with it. Many thanks.
