URGENT HELP NEEDED - Out of control what do we do?

Its getting worse. Today hes smashed in the wall by throwing a huge computer chair at it. Hes smashed the wardrobe door off the hinges.

We've tried and tried, but any attempt to even speak to him results in literally going from 0 - 1000 in a second. Hes shouts screams and punches the walls.

Today he went for my wife. Next step is going to be the police. We've been here before a month or so ago - took him to A&E out of desperation - they did nothing. All the useless tossers at CAMHS have done is tell us its bad parenting and to ring the police.

Hes 14 a big lad. As I've said before, hes got OCD and possible Aspergers. We've tried it all but he just does what he wants. Hes told his mother he wishes she were dead quite a few times. Last week he told me he was going to ring social services and tell them I was hitting him so I'd get arrested. I just just see it all heading down the slope into oblivion at the moment and he doesnt see it, doesnt care, or doesnt register.

I can't go near him at the moment but hes just a danger at the moment at times - We're so on our own because there is no-one to help!
