West Midlands Serious Crime Squad
At least 40 convictions failed in the 1980s as a result of likely malpractice. Beginning with the case of Paul Dandy in 1987, new forensic techniques were used to show when statements had been tampered with, usually adding incriminating phrases. As cases began to regularly collapse in the late 1980s, pressure mounted to investigate the squad. Clare Short raised the issue in Parliament in January 1989. The Birmingham Six's convictions were quashed in 1991. A series of other less high profile convictions based on the squad's investigations were quashed on appeal, including the cases of George Glen Lewis, Keith Twitchell, and on 17 October 2014, Martin Foran who had been wrongly convicted in 1978 for four counts of robbery. As of January 2017 a total of 60 appellants have had their convictions quashed. A total of over 100 cases either collapsed or were quashed on appeal.
