Rob Griffin, who held overall strategic command on the day of the Nottingham attacks in June 2023, has been promoted to deputy chief constable of Nottinghamshire Police despite admitting to multiple failures in the force's handling of the case. Three people—Grace O'Malley-Kumar and Barnaby Webber, both 19, and Ian Coates, 65—were stabbed to death by Valdo Calocane, who also used a stolen van to run over three pedestrians. The victims' families have expressed outrage, stating that the promotion represents a failure of accountability within British policing and a slap in the face to those affected.

Mr Griffin acknowledged that failing to detain Calocane—despite an arrest warrant being issued in September 2022—constituted a "complete failure". A public inquiry involving 164 witnesses uncovered further failings, including that families were not informed promptly of deaths, Mr Coates's body remained at the scene for 15 hours, and police failed to notify bereaved families that they were being stalked by another mentally ill man. The promotion, secured on 15 September, sees Mr Griffin move from assistant chief constable (earning approximately £123,152 annually) to a higher-paid position, whilst Nottinghamshire Police has referred itself to the Independent Office for Police Conduct.
