My sister and b-in-law had 3 young women move in next door. They immediately started throwing regular noisy parties. One party started at 12:00 on a Saturday and was still going at 03:00 on the Sunday. B-i-L finally cracked and went round to complain. They laughed in his face and told him to p*ss off ..
Eventually, the police got involved. They knocked on the door and were NOT told to p*ss off. The music was turned down, and there was a nice quiet street again.
But they watched the police car drive away and then they turned the music up again.
Another neighbour went round to complain and got into an argument with some of the drunken young men at the party, one of whom followed him home, tore the neighbour's garden gate off its hinges, and lobbed it through his window!
More police involvement ...
My B-i-L was starting to get seriously stressed by the behaviour of those morons, but then something wonderful happened ...
The girls started fighting over some good looking guy who they all fancied. (B-i-L could plainly hear what they were shouting.) The next thing, one of them got thrown across the room and went through a glass coffee table! Another neighbour knew the landlord and phoned him to tell him that his house was being trashed. The landlord turned up a few minutes later and was heard giving them notice to quit. They laughed in HIS face and told HIM to p*ss off, they knew their rights, etc. etc. The landlord turned and left.
An hour later, the landlord came back with several very large men. It all went quiet. Soon afterwards, the girls were seen taking suitcases out to several taxis waiting outside ...
