Operation Nimrod - The Iranian Embassy Siege

At approximately 11:30 on Wednesday 30 April the six heavily armed members of DRFLA stormed the Iranian Embassy building on Princes Gate, South Kensington. The gunmen quickly overpowered Police Constable Trevor Lock of the Metropolitan Police's Diplomatic Protection Group (DPG). Lock was carrying a concealed Smith & Wesson .38-calibre revolver,but was unable to draw it before he was overpowered, although he did manage to press the "panic button" on his radio. Lock was later frisked, but the gunman conducting the search did not find the constable's weapon.
