The UK's Independent Office for Police Conduct (IOPC), Britain's police watchdog, is investigating 11 officers — including a serving commander and a detective inspector — over alleged gross misconduct in their handling of an inquiry into a fatal road crash in Wimbledon, south-west London. Nuria Sajjad and Selena Lau, both schoolgirls, were killed in July 2023 when a Land Rover drove into the Study prep school during an end-of-term celebration; the driver was not charged after prosecutors accepted she had suffered an undiagnosed epileptic seizure. The IOPC confirmed it is examining whether officers provided false and misleading information to the victims' families and whether those families' racial backgrounds influenced how officers treated them, with the girls' families welcoming the inquiry and calling for the full truth to emerge.
