Three Leicestershire Police officers are under investigation for potential misconduct over their contact with triple killer Valdo Calocane.
Barnaby Webber and Grace O’Malley-Kumar, both 19, and 65-year-old Ian Coates were fatally stabbed in Nottingham on 13 June 2023.
The force had referred itself to the Independent Office for Police Conduct (IOPC), after it emerged officers were investigating a report Calocane had assaulted two colleagues on 5 May at a warehouse in Kegworth, Leicestershire.
Two police constables and a sergeant within the force have been advised they are now under investigation, the IOPC said.
