Vandalism or attempted burglary

Servus, the following story happened to me a few hours ago. When I looked out of the balcony, I saw a figure groping around my car. Teilkasko SB150, I snuck down to the guy, he noticed it and wanted to storm. I missed him one, but he managed to escape. I noticed on closer inspection that he wasn’t alone, but at least 3 people ran down the street. I rushed home to call the police when I saw him. I just heard broken glass on the phone. I went to the balcony and saw that the rear window was demolished. I went down when I arrived there, I saw sticks on the floor, which on the left side of both doors had smashed the window and smashed the rear window. And another dent on fenders and bonnet. The lock also got a lot! Meanwhile the police arrived and did not take any photos or a decent report, pressed mi r a criminal complaint in the hand, what it says: damage to the property of a car. I told them everything, but I don’t have a good feeling about it, since I think that the insurance will plead for vandalism, is the DEVK. What do you mean??? Thanks in advance P.S. was stolen nothing, have not yet been able to discover anything, was dark…
