“Something has happened but don’t worry, it is ok.”

Really? Not the words I'd use to describe this, and maybe the hospital had a rethink, because later - incredibly - there was no mention of it:

‘She said she would tell me when I came in to visit in the afternoon but when I got there they didn’t even mention it.

‘All I know is that Anthony woke up and he said the man had his hands round his neck and that someone must have pulled him off, and then they took him off.

‘He wasn’t all that good. I wouldn’t say he was dangerously ill but he just said he didn’t feel all that right. They kept asking him to drink water.

‘But Anthony was one of those people who didn’t like to make a fuss. He’d just say, “Oh I’m all right.”

But wait, you say, how was this allowed to happen in the first place? Wasn't he under guard?

Well, incredibly, the answer appears to have been 'Yes':

The UK Border Agency confirmed it is in the process of attempting to remove the Iranian man. A spokesman said: ‘We are reviewing this incident and, if necessary, will take appropriate action.

‘The detainee was handcuffed and accompanied by three escorts when the incident occurred.’

What were they doing?
