Rebekah Arter, 47, was found dead in Barbados in 2024. A coroner has since found that a Met computer error probably delayed her husband’s arrest, and warned ministers that similar deaths could happen.
Warren Arter, a former Metropolitan Police detective inspector, filmed the hotel room in Barbados where his wife’s body was found and said it “looks like chocolate but it’s blood”, the BBC has reported. Rebekah Arter, 47, died on 28 June 2024. Her cause of death remains unknown, and the coroner did not rule out unlawful killing. Her family say her death was not properly investigated, and a coroner has found that an error on a Met computer system probably stopped her husband being arrested months earlier. The BBC’s Panorama programme The Predator in the Police is due to air on 17 November.
What happened in Barbados
Mr Arter, 54, phoned hotel staff to say his wife was “unwell”. When they arrived, they said she was clearly dead. He gave several accounts of the night: that she had choked, fallen and banged her head, and that he had simply woken to find her dead. He also said he had slept for 18 hours and told Rebekah’s daughter-in-law, Lacey Usher, he feared he had been spiked.
A security guard told the BBC that Mr Arter did not appear to grieve and tried to go to a street party to “clear his head”. The guard said he then cried “crocodile tears” and attempted “performative CPR”, even though Rebekah’s lips were blue. Mr Arter recorded a video of the room, in which he can be heard making the “chocolate” remark, and sent it to friends and relatives. The BBC also reported that one of the officers who attended in Barbados still has a photograph of her body on his phone.
A Barbados pathologist found no evidence of violence, and the death was not treated as a homicide. A coroner said hair samples indicated “the occasional use of cocaine”. The BBC reported that the Barbados authorities failed to preserve evidence and did not interview hotel staff about Mr Arter’s behaviour.
Rebekah’s family asked the Met to send its own detectives to Barbados. The force told the BBC it did not, because no allegation of criminality had been made. Mr Arter attempted to take his own life in Barbados before flying back to the UK. He was arrested at Heathrow in connection with alleged sexual offences against another woman, whose case he had investigated as a police officer in 2010. Three days later, he was found dead in Wandsworth prison.
The coroner’s findings
Rebekah’s inquest concluded with an open conclusion in August 2025. The coroner said intoxication was a likely factor, but he expressly stated that unlawful killing could not be excluded. He declined to widen the inquest into a full examination of seven years of police misconduct investigations, and rejected the family’s argument that Article 2 of the European Convention on Human Rights was engaged.
The coroner, Professor Andrew Harris, later issued a Regulation 28 Prevention of Future Deaths report, a revised version of which was published in July 2026 after High Court proceedings on 4 March. It concluded that weaknesses in identifying domestic abuse and coercive control in investigations into police officers posed a wider risk. It was addressed to the Home Secretary, the Justice Secretary, the Independent Office for Police Conduct (IOPC) and the Metropolitan Police, and called for the wider implications of police officers abusing their powers against women to be considered nationally.
The report found that the IOPC passed the Met a sexual-offence report on 25 March 2024, after a witness described messages allegedly sent by Mr Arter following his dismissal. Errors involving the Met’s Connect computer system stopped the report reaching the right investigative unit. The mistake was not found until 3 July 2024, five days after Rebekah died. The coroner concluded that without it Mr Arter would probably have been arrested and remanded in custody. Even if he had been bailed, a non-contact condition would probably have been imposed, which might have separated the couple before the holiday. That is a retrospective assessment, not proof that her death would have been prevented.
The coroner also found that investigators knew Mr Arter had misused police powers and had inappropriate relationships with numerous women, but the possible risk to his own wife was not adequately considered when he was dismissed in May 2023. A senior detective later described him as an exceptionally persistent offender against women, though he had never faced criminal charges relating to that wider pattern. Repeated unexplained bruises and injuries were identified as potential warning signs that were available to investigators in 2024.
The earlier misconduct inquiries
The IOPC’s published response says its investigation, Operation Venta, identified seven potential victims of abuse of position for sexual purposes, among them Rebekah, who was referred to as Ms G. The Met began investigating in 2016 and the IOPC took over in 2017. It split the work into three parts:
- Operation Venta 1: alleged abuse of police position for sexual purposes.
- Operation Venta 2: misuse of police computer systems and inappropriate involvement in a criminal investigation.
- Operation Venta 3: allegations of illegal drug use.
The inquiries concluded in 2020 and were referred to the Crown Prosecution Service, which decided not to bring criminal charges at that time. The disciplinary process was delayed while Mr Arter received cancer treatment, and the drug-related proceedings ended in his dismissal in May 2023. He had spent seven years on full pay before the hearing, which heard that his misconduct stretched over 13 years. He had been placed on a police barred list for at least five years.
The allegations concerning Rebekah first came from an anonymous Crimestoppers report in January 2016. The IOPC says she never personally made an allegation. In 2017, investigators decided not to give her formal interested-person status, reasoning that she was married to him, had not complained and was likely to stay loyal to him. They searched the couple’s home in 2018 and examined her phone, and she declined to give a formal statement. The IOPC said its search was limited to evidence relevant to the original misconduct inquiry, and was not designed to look for domestic abuse because none had been alleged at that stage.
In its response, the IOPC said it had no jurisdiction over the March 2024 allegations, because they related to conduct after Mr Arter’s dismissal, and no direct access to the Met’s Connect system. It has committed to reviewing its safeguarding guidance for officers’ spouses and partners. It maintains that the information available before Rebekah’s death did not establish a specific risk of domestic abuse to her.
The Information Commissioner’s Office upheld the IOPC’s decision on 19 March 2026 to withhold the full Operation Venta report under the Freedom of Information Act. It concluded that protecting outstanding legal proceedings outweighed the public interest in disclosure at that time.
The family’s account
Rebekah met Mr Arter in 2006, when he was investigating domestic violence allegations she had made about a previous relationship. A court heard previously that she “changed drastically” during the relationship and did not want to go on the Barbados holiday. At the time of her death, UK police were investigating allegations of coercive control by Mr Arter.
Her son, Elliot Usher, told the BBC that when he first met Mr Arter at the age of seven, he felt “quite secure” because he was a police officer. He said Mr Arter later used “disgusting” names for his mother and controlled her, including her clothes, which changed from jumpers and jeans to “revealing skimpy outfits”. After her death, he found a variety of drugs and hidden CCTV cameras in the house, and explicit pictures of his mother, naked and bruised, apparently taken without her consent. A court in Croydon heard previously that Mr Arter would abuse her, watch pornographic films in front of her, and have cocaine dealers calling at the house.
The Met’s response
Commander Simon Messinger said: “Our thoughts at this time remain with Rebekah Arter’s family, who understandably have questions about the circumstances of her death. We would urge any victim survivors of rape and sexual offences, no matter how long ago a crime may have occurred, to reach out.”
In its formal response to the coroner, dated 12 December 2025, the Met said its Operation Onyx reviewed historic allegations of sexual and domestic abuse involving 1,636 officers and staff, and that 378 had since left through dismissal, resignation or retirement. Those are different outcomes and do not mean all were convicted. The force said arrests of its personnel for sexual or domestic abuse offences rose from 89 in 2022 to 137 in 2024, which it presents partly as evidence of increased reporting and enforcement, and that internal whistleblowing reports rose from 405 in 2021/22 to 1,389 in 2024/25. Its specialist domestic abuse and sexual offences unit has four investigation teams and a victim-support unit that was helping about 180 people in December 2025. The Met has also introduced mandatory training to help officers spot colleagues abusing their position for sexual purposes. These figures do not all relate to Mr Arter.
