Three officers are under investigation over their inquiries into alleged assaults by Valdo Calocane before he killed three people in Nottingham, the police watchdog has said.
The Leicestershire Police officers may face charges of potential misconduct as a result of how they investigated allegations against the triple killer the month before Grace O’Malley-Kumar, Barnaby Webber and Ian Coates died, the Independent Office for Police Conduct (IOPC) said.
Two constables and a sergeant have been told they are being investigated over how inquiries were progressed, the IOPC said.
It is claimed that Calocane assaulted two colleagues at an industrial estate in Kegworth, Leicester, in May last year.
The following month, he went on to kill students Mr Webber and Ms O’Malley-Kumar, along with caretaker Mr Coates, in a knife rampage in Nottingham.
Calocane, 32, was handed an indefinite hospital order for the manslaughter by reason of diminished responsibility of Grace O’Malley-Kumar, Barnaby Webber and Ian Coates, and the attempted murder of three others last June.
The attacker’s guilty pleas were accepted after medical evidence showed he has paranoid schizophrenia.
The judge at his sentencing said he would be detained at a high-security hospital “very probably” for the rest of his life.
