Mrs Webber added: “Like the NHS, the IOPC have also sought to gag us from speaking publicly and have forced us to sign NDAs saying we will not reveal their reports and findings.
“I now call on the IOPC to do the right thing like the NHS did and disclose their reports to the public so that full scrutiny can take place.
“It is the only way that real lessons are going to be learned and lasting change put in place so that no other family should have to endure the torture that we are.”
Radd Seiger, an adviser to the victims’ families, said the IOPC’s decision to impose an NDA was “inexcusable”.
He said: “It is inexcusable for any watchdog to seek to gag families of victims of serious crimes in this manner.
“That practice must be stopped.”
The watchdog said it anticipated being able to publish the findings and outcomes of the investigation “in the coming weeks”.
Derrick Campbell, director at the IOPC, added: “We completed an investigation into Leicestershire Police contact with Valdo Calocane prior to the killings and in particular the actions and decisions of officers investigating alleged assaults by him.
“In order to share our report and underlying evidence with the families of his victims at the earliest opportunity, a confidentiality agreement was needed.
“It remains in place until an appropriate time when the investigation findings and outcomes can be published, which we anticipate being able to do in coming weeks.”
The IOPC is also investigating the prior contact Nottinghamshire Police had with Calocane before the killings.
The force previously admitted it should have done more to arrest him sooner, revealing that an arrest warrant was issued in September 2022, over the alleged assault of a police officer in 2021.
