Cuff him Danno!

Picture in the paper this morning of this "rogue trader" bloke who it appears has managed to lose a Swiss bank a lot of money, as he was coming out of the magistrates' court after being remanded in custody.  But why was he in handcuffs?  The offence of which he is accused is a "white-collar" one and as far as I am aware there is no suggestion that he is violent or aggressive, so why?  Is this yet another unpleasant feature that we have copied from the Americans?
