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 on 13 June 2023.
The force had referred itself to the IOPC, after it emerged officers were investigating a report Calocane had assaulted two colleagues on 5 May at a warehouse in Kegworth.
Two police constables and a sergeant within the force, have been advised they are now under investigation, the IOPC said.
The force previously said no-one was seriously hurt and Calocane had reportedly been escorted off-site by security before police arrived.
