I live in a relatively peaceful town. However, for the last few days, there are 10-15 teenagers age 13-16 gathering right in front of my house and acting out really loud. Playing loud music, swearing, screaming etc. Trouble is, it is too close to my garden \~1m and they can directly see into my house through patio door.

First I tried to warn them. I came out and explained the noise is too much and kindly asked them to lower the volume. They did. However after I walked inside, the music got louder and they started dancing and taunting looking directly inside. Well I went outside again and asked what the deal is, again kindly, as an adult. Group's insigator kid started swearing at me and threatening me. He was also saying we are minors in between lines for some reason. I also find a hip chain in my garden, either thrown or placed. One of the kids walked over and I handed the chain to him, he dapped me and I walked back inside my house after the situation seemingly de-escalated. They started again afterwards and this lasted until 21:30 with addition of glares inside, verbal harrassment. I called the police.

2 police officers first spoke to the kids I assume, then spoke to me and my wife seperately at the same time. In the end, they didn't find our complaint serious and marked it as a noise complaint and basically dismissed us. I asked if it is ok for them to be this loud, and he said it is a public place so yeah. He also warned us not to video them as they are minors?

Second day, we were psychologically in a terrible state, couldn't eat or sleep. Our landlord advised us to stay in and don't show ourselves, hoping them to get bored to leave. We closed the patio door and blinds in this summer heat and stayed inside. This encouraged them and they started walking, and riding bike in my garden, banged on my patio door, threw a rock which damaged the door frame, and throw socks at my garden. We made another official complaint to the police online. Called my landlord and the police again on the 3rd day.

Landlord installed fences to keep them out and contacted police himself as the rock thrown caused damage to his property. A nice police officer came and explained the situation, said they will increase patrol in the area, hang a sign stating increased patrol, and check the cameras nearby for evidence of rock thrown. I also asked about video evidence which he said it is ok as it is a public place and to avoid crime. He left and came back shortly to say that they have identified and asked if we want to press charges. We said no, to not escalate the situation (they know our address) and the officer said he will speak with the kid's father. After that day, we felt more at peace.

Come today, kids are bit more controlled with noise, but they are still acting like animals. We learned that there are multiple complaints and they even vandalised the public area, throwing shopping carts, littering etc. Apparently police weren't a deterrent for these kids.

It almost feels like law is on their side to do whatever they want. I can understand it is a public place but the whole neighbourhood is suffering because of them.

What to do in these type of situations?
