The victim of a miscarriage of justice spanning more than 30 years is planning to sue the police for allegedly 'bullying' him to confess to a murder he did not commit.

Coffee shop worker Oliver Campbell, 55, has severe learning disabilities after suffering brain damage as a baby.

He was jailed for the fatal shooting of Baldev Hoondle during a robbery at a shop in Hackney, east London, on July 22, 1990.

Campbell spent 11 years in jail and a further two decades out on license before his conviction was quashed by the Court of Appeal last year after 'compelling' new evidence came to light.

His legal team now plan to launch a civil lawsuit in a bid to secure compensation for Campbell, accusing the Met police of exploiting the symptoms of his condition - which include a struggle with memory, concentration and retaining information - to extract a confession, The Mirror reported.
