Under a railway bridge on Salmon Lane in the Limehouse area of East London is an inconspicuous piece of graffiti left in large white letters, ‘G. DAVIES IS INNOCENT’. The graffiti is one of the few remaining pieces painted in the 1970s as part of a grassroots public campaign to have George Davis freed from prison. In 1974, Davis was sentenced to twenty years in prison for the robbery of the London Electricity Board in Ilford. After family and friends raised questions about the evidence used to convict Davis, the phrase ‘George Davis Is Innocent OK’ began appearing all over East London and the rest of the country. The campaign paid off and in May 1976 Davis was released under the royal prerogative on the advice of the then home secretary, Roy Jenkins. However, only 18-months later, Davis was caught robbing the bank of Cyprus in Holloway and pleaded guilty to his involvement in this armed bank raid.
