made their testimony dubious. Several of the officers involved failed to turn up to the appeal hearings. Ronald, Donald and John Brown, also convicted for the robberies, had their convictions overturned later, in two separate appeals. George Glen Lewis Lewis was arrested in January 1987 and subsequently convicted for two armed robberies and a burglary. His case was examined by the Yorkshire Police during their investigation. He told the Court of Appeal that be was "head-butted, punched and threatened with a syringe as he was questioned". He was forced to sign a confession and was racially abused.
