On 22 July 2005 , Jean Charles de Menezes , a Brazilian electrician living in London , was shot dead by plainclothes police officers at Stockwell station . This incident came a day after the failed 21 July 2005 London bombings occurred on Tube trains and a bus in London ; however , it later emerged that it was a case of mistaken identity on the part of the police and that Menezes had nothing to do with the attacks . In the immediate aftermath of the shooting a small shrine to de Menezes was created by mourners outside the station . This evolved into a permanent memorial mosaic which was unveiled on 7 January 2010 at the station . It was made by local artist , Mary Edwards , with the help of Menezes ' cousin , Vivian Figueiredo , as well as Chrysoula Vardaxi
