Mr Ganidagli, 24, said: "Ahmet was outside having a smoke and Huseyin was looking after the till when the motorbike came. The men got off the motorbike and shot Ahmet and then went into the shop and shot Huseyin as he was coming out to defend his dad. It must be a case of mistaken identity." He added that Huseyin was undergoing surgery but was expected to survive. "The whole family is devastated at Ahmet's death. Ahmet was loved and respected by all who knew him." Mr Paytak, who lived in Islington, leaves behind three children, Huseyin, 21, Kemel, 27, and daughter Elif, 25.
