Serious Crime Squad

The West Midlands Serious Crime Squad was a police unit in the English West Midlands which operated from 1974 to 1989. It was disbanded after an investigation into allegations against some of its officers of incompetence and abuses of power.

Several resulting miscarriages of justice were later overturned on appeal, including the cases of George Glen Lewis, Keith Twitchell the Birmingham Six and on 17 October 2014, Martin Foran who had been wrongly convicted in 1978 for four counts of robbery. As of October 2014 a total of 33 appellants have had their convictions involving the squad quashed.
