Don't know what to do? At our wits end?

My brother, who is 40-odd has got Paranoid Schzophrenia. The worse it's been is the last three years. We've had to repeatedly get the police involved, because he's not took hos medication, therefore leading him to be aggressive towards me and my mother.

This year is the fourth year, and he seems to be getting worse. This past week, he's had £30+ from my mum. I know people will say: "Stop giving him money." It's not as simple as that. If he doesn't get it, he refuses to go until he does. If we call the police, he asks later on in the day or the day after.

What happened tonight is the last straw for me and my mum. He came up our house at 8PM, wanting to stay at ours. He also wanted the taxi paying for him.

Just this night alone, he's had £15 from both me and my mum. He came our house screaming and shouting, and we can't deal with it anymore. We've told his nurse, crisis team, etc but nothing's been done. What else can we do?
