I have this exact problem. A 40+ year old man having parties (including during lockdown, police did nothing) every week. Starts on Thursday and goes non stop until Monday or Tuesday. Music, guitar, singing, shouting, banging. He's a dick, so is his mates. They made a song about corona when it was at its worst and thought it was hilarious. They also think they're cool for playing spoons?! He sells drugs, has been called a pedalo and had his car windows smashed so he's obviously not well liked. One of the times we phoned police during lockdown he threatened my husband so we haven't phoned them since and just live in fear with constant anxiety, no sleep and headaches.
All my other neighbours are great, so friendly and lots of cute dogs!
He hasn't been called a pedalo, it changed my word so he's been called a thing to do with kids.
