On 101 obviously because I feel he is harassing me. I am not usually one to involve the police in neighbourhood disputes and it feels a bit petty to me so would like other views.
Council moved us into a 2nd floor flat last year. I have 4 DCs, youngest aged 2. We did not bid on this property, council forced us to take it or otherwise they would evict us from the temp house they had put us into as we were homeless.
I initially chatted and introduced myself to ground floor neighbour (Dave, he has a 3 bed flat to himself but I digress) as I wanted to make the best of it and hoped the neighbours would be friendly.
After a few days he started talking about a former neighbour who lived below us, telling me that she had made loads of complaints about him to the council regarding the 'shared garden'. He has put up radio aerials as he is a CB buff, one of them is a spiky contraption, loads of metal rods sticking out about 5 ft off the ground. Anyway, he was referring to this woman as a 'silly bitch' 'uptight cow' etc and saying how she thought she could get 'one over' on him but 'I've lived here for 30 years' blah blah blah. He also put a padlock on the 'shared' garden gate as druggies congregate there apparently but said I could pay for my own key if I wanted one. I had already decided that DCs would not be going in the garden due to the aerials and the fact that the 2 flats below would be overlooking them and I did not know who the neighbours were.
Shortly after that, Dave told me that he found some Lego in the garden (obviously my DCs, DS2 must have thrown it out of the window) but he would not give it back as it would probably get thrown again 
. I ignored.
When the weather got warmer, I set up a water table for my toddler to pour water and splash in on the balcony. There is a drainage hole in the side of the balconies for water to run into a overflow pipe which then slowly drips down onto the garden on the back balcony and the path at the front balcony. I noticed 'Dave' standing below my balcony swearing to himself ('what the fuck' etc) when my toddler had poured some water onto the balcony and it was draining off. I also used to wash down the balconies with a bucket of water when they got dusty. This sent Dave nuts although he was rarely in the garden and I never did it if he was out there. He told me that I should not be pouring water on the balcony as the drainage pipe is for rainwater only and he was going to complain to the council. The council later sent me a letter telling me not to 'throw water over the side of the balcony' which I was not doing anyway. So I just thought .
From that point on, I decided to ignore Dave as he is obviously an arse. This was last summer.
Last Friday, myself and DC were going in the front door of the flat block when the toddler shut the main front door which has been pulled open (Dave had taken it upon himself to screw hooks onto the front and rear entrance doors so he could keep them all wide open for what reason I know not). Dave, who was in his garage across the road, started shouting loudly 'that little fucking cunt shuts that door again and I'll have him'. I was shocked but ignored and walked on.
On Monday, I scrubbed my back balcony for the first time since last summer and poured a few buckets off water over it. I later get into my car and wonder why the windscreen is filthy with mud all over it. I get out and notice that it looks like someone has chucked mud and water all over the car. I know it immediately it was Dave so I knocked on his door and asked what he'd thrown over my car. He admitted it and told me 'you've upset everyone in this block and you need to watch it cos you need to live here' actually spitting with rage and shaking. I decide to log it with the police because my older DCs witnessed all this and were a bit shaken. I also informed the council who want a meeting with me next week.
Dave has since covered the 'shared' garden's patio below my balcony with tarp!
Today, I parked up with DCs and as I get out of the car, Dave and another neighbour are standing at his van, Dave says 'don't you look at me or I'll have yer'. I told him I wont be bullied by him and I have informed the council so he says 'go on then, fucking go on, arrogant cow'. I ask him to repeat what he said so he says 'I did'nt say anything did I and I've got a witness', this to the old man who lives opposite him.
I have reported to the police again. They said they would come out but have not.
The neighbours (a single man and his adult son) below me have shouted up before about my toddler, 'shut up you little shit' when he's had a tantrum. Also heard them shouting about 'the fucking cunts upstairs' and throwing things about. Son has violent rows with his girlfriend in his flat and outside late at night waking up the DCs. He also played loud bass music (floor shaking) during the day, so loud I could'nt hear the TV and I knocked a few times and asked him politely to turn it down. He used to get up at around 11am, put the music on and keep it on until around 2pm every fucking day while his dad was out at work. Toddler could not nap. He told me he can play music if he likes in the day. Eventually stopped a few months ago. I am assuming that is how I 'upset' them. Oh they also chain a bike to the rails on the landing outside their flat which makes it difficult to walk through with bags etc so I asked the council to get them to move it (I was told I could not leave a buggy on the landing when I moved in). They did for about a week then put it back.
I am an tenterhooks with the DCs making noise and even more stressed than usual if that is possible. I feel panicky about leaving my flat and am avoiding it as Dave is always outside. I feel silly contacting police though. AIBU?
