Hello,
there was a police operation in our neighborhood last night, a bit further away. I only overheard it by chance while out for a walk. I just heard a few noises, like "ouch," and a beer bottle breaking. Apparently, several teenagers had broken into the house, while these teenagers, whom I don't even know, told me that the landlord or owner had hit one of their friends and another had threatened them with a chainsaw. Then they ran off. I told them to keep quiet, consult a lawyer, and then contact the police. Even here in Germany, you can get into serious, unnecessary trouble if you don't have legal counsel or don't know what you're doing. But whether any of it is true, I don't know. Anyway, if you hear that a criminal complaint or summons will probably arrive in the mail in a few weeks, you should be prepared, if possible.
