Police are offering a £20,000 reward for information about the murder of a man in east London.
Wayne Stockdale, 42, was shot in the head in Bow in May 2011. He was attacked in an underpass under a block of flats, near the junction of Knapp Road and Rounton Road.
Police believe that he may not have been the intended target of the shooting.
It's believed that two men - described as black or Asian and with covered faces - opened fire with handguns, shooting at him and into the street.
