Lewisham (South London News) February 26, 2026 – A damning investigation has revealed that a critical anonymous call reporting double-murderer Carl Cooper as having killed someone was dismissed as a hoax by Metropolitan Police officers, just days before one of his victims was reported missing. Carl Cooper, 66, received a life sentence in 2024 for the brutal murders of Naomi Hunte, 41, and Fiona Holm, 48, both of whom had endured his violence and sought police help beforehand. The Independent Office for Police Conduct (IOPC) has now issued disciplinary notices to ten Met Police officers, spotlighting systemic failures in protecting vulnerable women from a known dangerous individual.

What Happened in the Hoax Call Incident?

The pivotal call, logged on June 25, 2023, came from an anonymous tipster who explicitly stated that Carl Cooper had murdered someone that week, according to an IOPC spokesman. This warning arrived mere days before Fiona Holm was reported missing, underscoring a potentially life-saving opportunity squandered. A police constable in the Met’s control centre marked the call as a hoax, a decision now under formal misconduct scrutiny, with the officer served a notice last month.

As detailed in the IOPC’s public statement, the anonymous caller directly named Cooper in connection with a fresh murder, yet the report was not escalated or investigated meaningfully at the time. This oversight forms part of a broader probe into how police responded—or failed to respond—to prior complaints from both Naomi Hunte and Fiona Holm about Cooper’s violent behaviour.

Who Is Carl Cooper, the Double-Murderer?

Carl Cooper, a 66-year-old handyman from the Lewisham area, was convicted and jailed for life in 2024 following a trial that horrified South London communities. He murdered Naomi Hunte, 41, by stabbing her in the chest, an act of shocking brutality. Separately, he killed Fiona Holm, 48, whose body has never been recovered, leaving her family in agonising uncertainty.

Both women had been in romantic relationships with Cooper, roughly a year apart, and each had suffered his violence sufficiently to contact police for assistance. Cooper’s pattern of domestic abuse and control emerged clearly in court evidence, painting a picture of a predatory individual who exploited his position of trust.

Who Were the Victims, Naomi Hunte and Fiona Holm?

Naomi Hunte, aged 41 at the time of her death, was stabbed in the chest by Cooper in a targeted attack that ended her life prematurely. Fiona Holm, 48, vanished after her involvement with Cooper, with her body never found despite extensive searches; she was officially ruled murdered based on compelling evidence.

Crucially, both women had reached out to the Metropolitan Police regarding Cooper’s violent conduct during their relationships. These complaints, lodged separately but linked by the same perpetrator, represented clear red flags that were not acted upon decisively enough to prevent tragedy.

When and How Did Police Disciplinary Actions Begin?

Ten Metropolitan Police officers have been served with disciplinary notices as part of the IOPC’s ongoing investigation, an IOPC spokesman confirmed. These notices relate to the force’s contacts with Naomi Hunte and Fiona Holm prior to their murders, encompassing everything from complaint handling to call management.

Among them is the control centre constable who dismissed the June 25, 2023, hoax call mentioning Cooper; this officer received a misconduct notice last month. The IOPC’s probe, now in its advanced stages, examines whether procedural lapses, misjudgements, or institutional biases contributed to the failures.

Why Was the Anonymous Call Dismissed as a Hoax?

The IOPC spokesman explained that the caller anonymously asserted,

“Cooper had murdered someone that week,”

yet the report was categorised as a hoax without further verification. This occurred in the Met Police’s control centre, where high-volume calls often demand rapid triage, but critics question whether bias against anonymous tips or overload played a role.

The timing—June 25, 2023, just days before Fiona Holm’s disappearance—amplifies the gravity, as an inquiry might have uncovered Cooper’s escalating danger. IOPC investigations into such calls typically assess if officers followed protocol, applied reasonable suspicion thresholds, and documented rationale for hoax labelling.

What Prior Complaints Did Victims Make to Police?

Both Naomi Hunte and Fiona Holm complained to police about Carl Cooper’s violence while in relationships with him, approximately a year apart. These reports detailed physical abuse and threats, yet did not result in arrests or sufficient safeguards, allowing Cooper to strike again.

The IOPC is dissecting these interactions, including officer responses, risk assessments, and any follow-ups—or lack thereof. Families of the victims have long voiced frustration over perceived police inaction, a sentiment echoed in similar domestic violence cases across London.

How Has the IOPC Responded to These Failures?

The Independent Office for Police Conduct (IOPC) launched its investigation following referrals from the Metropolitan Police, focusing on pre-murder contacts with Hunte and Holm. A spokesman noted that ten officers now face disciplinary proceedings, signalling potential gross misconduct findings.

The watchdog’s role ensures accountability, with outcomes possibly including dismissals, retraining, or policy reforms. IOPC chair Rachel Kemp has previously stressed the need for cultural shifts in handling domestic abuse reports, particularly those involving vulnerable women.

What Broader Issues Does This Raise for Metropolitan Police?

This case exposes recurring challenges in the Met Police’s approach to domestic violence, where complaints from women like Naomi Hunte and Fiona Holm too often falter. Statistics from prior years show thousands of such reports annually, yet conviction rates remain low amid resource strains and victim reticence.

The hoax call mishandling exemplifies triage pitfalls in busy control rooms, where anonymous tips risk dismissal despite credibility indicators like specific naming of suspects. South London boroughs like Lewisham, with high crime densities, amplify pressures on frontline responders.

When Was Carl Cooper Convicted and Sentenced?

Carl Cooper was jailed for life in 2024 after a thorough trial at the Old Bailey, where juries heard harrowing details of Naomi Hunte’s chest stabbing and Fiona Holm’s unsolved disappearance. The judge highlighted Cooper’s lack of remorse and the premeditated nature of both killings.

Sentencing remarks emphasised the betrayal of trust by a handyman known in the community, whose crimes shattered families and eroded faith in protective services. Cooper’s minimum tariff was set, ensuring he poses no further threat.

Why Is Fiona Holm’s Body Still Missing?

Despite exhaustive searches, Fiona Holm’s body, 48, has never been located, a heartbreaking loose end in the case against Carl Cooper. Investigators believe he disposed of it meticulously, but appeals for information continue, with rewards offered.

This absence compounds grief for Holm’s loved ones, who seek closure. Cooper has provided no leads, maintaining silence that frustrates detectives and underscores murder probes’ complexities.

What Impact Has This Had on Victims’ Families?

Families of Naomi Hunte and Fiona Holm have endured profound loss, compounded by revelations of missed police opportunities like the hoax call. Public statements from relatives decry systemic letdowns, fuelling calls for justice reforms.

Support groups in Lewisham highlight how such cases retraumatise communities, with vigils held for Hunte and Holm. Their stories humanise statistics, pressing authorities for change.

How Can Police Prevent Similar Tragedies?

Experts advocate mandatory risk tools for domestic reports, enhanced anonymous tip protocols, and specialised training. The IOPC’s findings could mandate Met-wide audits, ensuring calls naming suspects trigger automatic checks.

Collaboration with charities like Refuge emphasises victim-centric policing, prioritising safety over bureaucracy. South London’s diverse populace demands culturally sensitive approaches to build trust.

What Is the Current Status of the IOPC Investigation?

The IOPC probe remains ongoing, with disciplinary processes against the ten officers—including the hoax call constable—advancing. Final reports may recommend force-wide changes, per the spokesman.

Public updates promise transparency, vital for restoring confidence. Outcomes will inform national standards, potentially influencing policy under Home Office scrutiny.
