I don't know whether the school was informed.
I was alone decorating in the front downstairs room in the few weeks before I moved in. I had painted the window frame so the window was open and there were no curtains. I heard the obscenities and turned to look and there he was close up to the window performing in the light. I ran to the door and locked it and shouted through the letter box for him to clear off.
If you ever go past the bottom end of Lord St #26 - you will see that the end house has a much lower garden wall than the others. I lowered it - he had hidden behind the high wall that was, so that only I would witness his display.
