I'm asking you for help today to help my girlfriend.
Context: she moved 6 months ago to an apartment. The price is reasonable and the location too. Very quickly, she noticed a problem: her adjoining neighbor is crazy.
My girlfriend's room overlooks one of the rooms in his apartment. He knocks on the walls when she makes the slightest noise (he knocks so hard that we hear things between the walls falling), uses low-pitch noise to prevent her from sleeping and insults any person who dares to approach his door. In addition, he installed a camera overlooking the front door but also that of my girlfriend; he can therefore film the people coming and going and listen to the conversations (the walls are thin).
It's consuming her life. Unfortunately, there is nothing I can do to counter it. This man is a ghost: no name on his door or on his mailbox. He never leaves his house, and only two people in the building have seen him: he's supposedly stocky, in his forties, and hairy. He's said to have tagged swastikas in the elevators to take revenge on a Jewish neighbor, threw engine oil on the stairs of the building on New Year's Eve, and more. But we have no evidence of anything except the camera installed in front of his house.
Unfortunately, French justice stipulates that the trustee of the building has to file a complaint for this camera and not my girlfriend.
How to get through to him? He encroaches on her private life, knows all her movements via the camera, and prevents her from sleeping. The situation is critical – we can't let him act with impunity.
