The Chandler's Ford shooting (codenamed Operation Hurlock by the police) was the shooting of armed robbers in the town of Chandler's Ford, Hampshire, in southern England, on 13 September 2007. Two men were shot dead by Metropolitan Police officers while they were robbing a cash-in-transit van at gunpoint. The Metropolitan Police's Flying Squad had been tracking a gang of armed robbers from South London who were estimated to have stolen £500,000 (£876,000 today) from 18 robberies of security vans. The Flying Squad received intelligence that the gang intended to target the HSBC branch in Chandler's Ford and planned to lie in wait and apprehend the suspects as they attempted the robbery.
Armed police officers arrived in Chandler's Ford in the early hours of the morning of 13 September and concealed themselves in a public toilet close to the bank, supported by snipers in overlooking buildings. At 10:05, shortly after the arrival of the G4S van, Mark Nunes (wearing a mask) approached the guard and pointed a gun at him, demanding he hand over the cash box. A police sniper opened fire, hitting Nunes in the chest. As officers were deploying from their hiding place, a second gang member, Andrew Markland, ran over and picked up Nunes's weapon; he was shot twice by a second sniper. Police officers attempted first aid but Markland died at the scene. Nunes was airlifted to hospital but died later that day.
At the trial of the remaining gang members, the jury was shown footage from a police surveillance post at Chandler's Ford, including the moment Nunes and Markland were shot. The shooting was investigated by the Independent Police Complaints Commission (IPCC), which concluded that the armed officers had acted properly, though it found flaws in the planning of the operation. An inquest held in 2011 reached a verdict of lawful killing, after which the IPCC published its full report, recommending that a firearms commander independent of the investigation be appointed to lead future operations. The Metropolitan Police implemented the recommendation.
