A disgraced Met detective inspector allegedly drugged his wife so men at swinging parties could rape her, it has emerged – before her body was found in a blood-drenched hotel room.Warren Arter, 54, was arrested following allegations of coercive control over his wife Rebekah, made by one of her relatives, as well as a litany of drug offences.Arter – who worked on a unit dealing with rape victims – was sacked for gross misconduct in May last year. This was after being suspended for six years on full pay due to taking drugs and offering to supply them at swingers’ parties. The disgraced detective was found dead in his cell at HMP Wandsworth earlier this year, less than a week after being charged with misconduct.He was due to appear at Woolwich Crown Court in July after he was charged with misconduct in public office after accusations he had inappropriate contact with a victim of crime. Now it has emerged that a fortnight before his death his wife Rebekah, 47, was found dead in a blood-soaked hotel room in Barbados – and her friends claim she was raped while unconscious after being drugged by Arter – who she had met when she had reported domestic violence. Former Detective Inspector Warren Arter was sacked over accusations he made sexual advances on victims and offered cocaine to women at swingers’ orgies Rebekah met Arter in 2007 when she reported a complaint of domestic violence to police and Arter was the ­investigator, a det­ective sergeant working on a community safety unit He was found to have breached the police standards of professional behaviour for discreditable conduct, authority, respect and courtesy, duties and responsibilities, honesty and integrity.

Six months after meeting Rebekah, he mov­ed into the home she shared with her young son Elliot in Welling, South London, and they married in Las Vegas in 2016 Photos from Arter’s phone which were used in evidence against him in his misconduct tribunalShe died from a massive haemorrhage of the lungs caused by a viral infection and cocaine was found in her system.One source told The Sun: ‘It apparently seemed like a murder scene with blood everywhere.’ An inquest into her death will take place at a later date in London.They said police were told Arter sent a video to a friend showing Rebekah having sex with a man while she seemed to be unconscious. Arter spent more than £3,000 on Rebekah’s credit card in Barbados in the days after her death.He reportedly gave differing accounts of how he found her body, saying they had been sunbathing and returned to the room, then he woke two hours later to find her dead.He  also said they went for dinner and he had slept for 18 hours before finding her dead.By the time ­Rebekah’s body was repatriated to the UK Arter had died in prison.It is estimated he earned around £400,000 since he was suspended by Scotland Yard in 2016 over allegations that he abused his position ‘for a sexual purpose’.He was accused of pestering victims of sexual offences between 2006 and 2013 when he was a detective sergeant leading a rape investigation team which won an award in 2009 for having the best detection rate in the Metropolitan Police.The officer offered to supply Class A drugs to several women and photographed himself in front of a line of cocaine.Arter spent two years buying cocaine and MDMA and sent out text messages offering to supply drugs to others while he was working in the Met’s Sapphire squad.Police found a photograph of the officer sitting on his sofa in front of a mirror with lines of white powder and a card on it resting on a coffee table in his living room.Another image showed plastic bags containing white powder resting on a set of digital scales. Former Detective Inspector Warren Arter was found unresponsive in his cell at HMP Wandsworth (pictured) less than a week after being charged with misconductHe was barred from policing after his sordid role in cocaine-fuelled parties where he turned a blind eye to drug taking and suspected exploitation was revealed in a police misconduct hearing.When police arrested the father as he flew home from Jamaica in December 2016, officers found drugs paraphernalia more commonly associated with a drug dealer at his property, including metal straws and mini scales found to bear traces of cocaine along with a grip-seal bag that had traces of MDMA.The officer was taken into custody where he tested positive for cocaine.He was interviewed under caution on suspicion of offering to supply controlled drugs to others and the corrupt or improper use of police powers for failing to act when he became aware of other people possessing and consuming drugs.A three-day misconduct hearing was told that the disgraced officer had bought cocaine and MDMA on multiple occasions between 2016 and 2018 and regularly attended parties where cocaine and crack were openly consumed, which he turned a blind eye to.Arter also failed to take action when he was aware a man was providing drugs to a woman in exchange for sex.The Independent Office for Police Conduct (IOPC) discovered text message exchanges in which he arranged to buy drugs, discussed taking them, and offered to supply cocaine to two women on two occasions.His phone and iPad were also found to bear traces of cocaine.He was found to have breached the police standards of professional behaviour for discreditable conduct, authority, respect and courtesy, duties and responsibilities, honesty and integrity.Despite the extraordinary length of time the case has taken, Arter was due to face a secondary disciplinary hearing over allegations he had abused his position for a sexual purpose.
