I told them I was supposed to be at court . I was told everything was fine . I was told everything was in order and I was being released . ' When asked about his brief period of freedom , he replied : ' I enjoyed the sunshine for a few hours . I sat on the bench 20 or 30 metres from the prison gate . I thought that they had released me by mistake and they should come and get me and take me back in . ' I was out of the prison for about three hours . There came a time when the prison officers came and fetched me . Many prison officers . ' The mistake happened three weeks into the first trial which cost approximately £3,000 a day .
