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.
I don't know anything about the law and Police powers in England, but in Scotland here is what happens.....
In my days in the Police I was once sent to attend a complaint of excessively noisy music from a flat in a rural town in Renfrewshire, this place being about 15 minutes drive from where I was stationed. 'Twas a Sunday night/early Monday morning and complainer couldn't get to sleep and had work in the morning etc... I noted statements from complainer and wife, and told them I was duty bound to give the offender a warning and request that he turned the noise down. I also told them that he would probably turn it back on as soon as we were out of sight, and that if he did, they were to phone us back as we were not going to be far away!
Predictably, the nobber failed the attitude test but agreed to be a good boy and turn the music down. We got in the Police car and I drove round the corner and waited - for all of 2 minutes when the complainer phoned in reporting the noise had started again. In Scotland we have the Civic Government (Scotland) Act 1982 which gives certain powers to the Police in these circumstances. I went back to the offenders flat and knocked on the door. He obviously couldn't hear for the noise, so the door got kicked in. The tenant didn't like this much so began shouting and swearing at us, for which he was arrested. In addition his stereo system was taken as evidence and would have been out of his possession for months. He was taken to the Police station 10 miles away and locked up for a few hours, before being released to WALK home!
We never did get another call to that address
