Elderly Brother-In-Law In Trouble

Hi,

Completely new to this, but not sure where to turn. My husband's brother (71yo) is notably mentally ill (diagnosed in his 20's I believe), hearing voices which tell him to deliver messages to the primary school children - and hence after many times of walking onto the school property over years, and numerous run-ins with the police, he is now to appear in front of the courts later next month. Next time he does it, prior or post the court appearance, its jail. He says he won't stop visiting the school regardless.

We take him to work with us most days, and other family members visit him on others, however those few days he is not with one of us, off he goes back to the school. He has been told by all the family, the school and the police to not visit - but he is of the delusion that it is his calling in life.

Last week we had a call from the real estate agent of the house we rent for him to say he had wandered into the neighbours house at 1am - they knew him, so no police or charges pressed, but obviously distressing.

There are many other obsessive behaviours - collection of plastic bags, feeding of birds, etc.

I do not think he would ever hurt anyone (he's very frail), but I am seriously worried for his safety - either someone hurting him, or possibly going to jail - he wouldn't last a day.

He has not been to a doctor in many years and has not been formally assessed, but shows many symptoms of schizophrenia. My husband can't grasp that this is the brother he used to look up to (13 years younger) and thinks we just 'see what happens'.

There has to be something we can do. Any advice would be greatly appreciated. Thank you.
