A former carer who worked with the young man, told The Sun: 'He's one of the most difficult and challenging mental patients I've ever encountered.
'He suffers from schizophrenia and has a tendency towards violence. He is stockily built — about 5ft 10in tall — and gets angry when he is denied something that he wants or is told what to do.
'Something must have gone seriously wrong at the Tate because he's not allowed out unless accompanied by at least two support staff. There will have to be a serious inquiry into what he was doing there.'Yeah, so the NHS mental health service can 'learn lessons'. Again.
Police are investigating whether the teenager escaped from his secure unit or managed to get free of one of his carers, and have confirmed mental health was being explored as a line of inquiry.They don't know yet? Surely that's the sort of thing that they could find out in 5 minutes?
