Three men are seen on the CCTV at the junction of Marcella Road and Serenaders Road at around 7pm on Thursday May 12.A man in a white shirt, upon realising one of the suspects has a shotgun, runs and dives behind a parked car before sprinting away.Moments later, the gunman appears to shoot the weapon over a wall and then takes a bicycle and flees the scene, followed by his two accomplices along Ferry Mews, in the direction of Brixton Road.Detectives from the Met’s Trident unit have released the footage in an appeal to identify the men, who are sought in connection with the attempted murder. Detective Constable Jo Ross, from Trident and Area Crime Command, said: “The 21-year-old victim was fortunate to recover from what were potentially life-threatening injuries at the time of the incident.”Other passers-by were threatened by having a shotgun pointed at them – these are dangerous people.”We are keen for the public to give us any information in relation to this appeal, who witnessed the incident or who recognises the suspects.
