I am currently digging. Heard from a German on twitter saying they received a letter from the goverment confirming this. I have since asked them to post a pic of the letter they recived. Will notify you when I get a response.

My takeaway from this is if the police suspect you to have some friends in your house who dont live there they can just walk in unannounced. Since public gatherings are limited to just 2 people. Please tell me if am mistaken.
