I have a friend who has some serious mental health issues, he has been sectioned for several months on 2 occasions I'm aware of.
He stopped taking his medication some weeks ago, against medical advice, and has been very proud of getting off it.
I very rarely see him, we have occasional text conversations but recently they've all been about problems with his neighbours. He does have an ongoing feud with one but he is detailing arguments/shouting matches with at least four neighbours plus random altercations with people in shops, etc.
The texts don't make much sense. The cause of the issue, eg dog barking, seems to be transferred between people in his mind, so several people are being blamed for one of the neighbours dogs barking.
I contacted a mutual friend who has heard gossip about our friend 'losing it' with people and driving around in a very dangerous and aggressive manner.
I do not know what, if anything, I should do? I know he sees his social worker regularly, possibly weekly. Is there any way for me to report a concern which would get to them? He says he has called the police on his neighbours several times. If that's the case would the police have to do a search on him and will there be some sort of flag to tell them to report to social services?
As I say his texts don't make much sense but it is obvious he feels victimised and that he is entirely blameless whilst others are attacking him for no reason. He's not a violent man so I don't think he would cause harm to others but I do think he could be a danger to himself.
