Ihave a few times.
one when a group were attacking a local Asian shop/halal butcher shop. It stemmed from racism for the abuse I heard being shouted. There was blood in the street after so there must have been violence but as far as I found out no hospital treatment and mob were all arrested.
2 different times for separate neighbours (different years, different areas) where I heard domestic violence. Very glad I called the second time as I heard her leave with a suitcase in the middle of the night never to be seen again after the police had picked him up after my call.
two different times for another neighbour who (is an arsehole) but has quite severe mental health issues.
1st time
in the middle of the night for a psychotic episode where he was smashing up his flat breaking the glass then throwing stuff including tv and furniture out the top floor windows running in and out of the house and up and down the street screaming etc. police came and I assume he was sectioned as he disappeared for a couple of months before coming back looking much better.
2nd time
he started screaming out of his back windows at a landscaper I had hired who at that moment was taking a wheel barrow of gravel round to another part of the garden to lay.
as I went out to see if the gardener was ok and why the neighbour was shouting the neighbour had managed to run down two flights of stairs and was running down the pavement full speed at him. While the poor gardener had a shovel in his hand in front of his chest like a shield crying Jesus protect me from this devil. Evil will not prevail the lord will protect me.
I jumped in between them and unexpectedly seeing me caught neighbour off guard so he stopped dead (luckily for me) I then with the gardener behind my back managed to manoeuvre him to my front door to get him in the house while shouting for dp to call the police and bring me the phone all With neighbour Screaming that I was an ugly witchy bitch and I can’t stop him. by this time dp had also come out and while he was still screaming I think my previous interactions before this when I caught him out bullying another neighbour with vulnerabilities had meant he knew he wouldn’t get away with scaring or intimidating me and dp was also there so attacking wasn’t an option anymore.
i intervened without really thinking about it because I knew the gardener had been hired by the team because they knew him through church (my friend knew them through her church so recommended team to me) as he was the pastors son, he had sen issues and other issues so it was a way for him to be in work but protected by his fellow church members in a job he liked and it helped his confidence etc. so I knew he was completely unable to cope with something like this!
anyway police came dealt with neighbour (no arrest) they told me he was quite obviously unwell but unless gardener wanted to press charges he wasn’t going to be arrested and was stable enough that no section was appropriate.
I called the landscaping team with the poor man crying in my hallway and they arrived and took him home and I never saw him again but heard he was shaken but ok. They replaced him with their biggest roughest looking man who obviously neighbour completely left alone. I was mortified as had I known I would have warned them in advance. They were ok with me about it. I still feel terrible about it though!
this neighbour then went on to try the same with another a fencer in the street a couple of months later so it was the first time with me but became a pattern!
he also now screams at a local dog walker with a yapping dog so I think noise sets him off.
