The death of a 29-year-old member of Saudi Arabia’s royal family in a west London hotel room resulted from a fatal cocktail of substances, an inquest has determined. Abdullah bin Fahad bin Abdullah bin Abdulaziz bin Musaed bin Jalawi al Saud, a 29-year-old prince, was discovered fully clothed on the bathroom floor of his room at the Marriott Hotel in Kensington on Nov. 25, 2025.
Testing conducted after his death revealed extreme levels of intoxicants in his body. His blood alcohol content measured 222mg per 100ml of blood—nearly triple England’s legal driving threshold of 80mg. The inquest learned this concentration alone could induce a coma.
Additionally, potentially lethal quantities of gamma-hydroxybutyrate (GHB)—widely known as a “party drug”—were found in his system. Cannabis traces were also detected, along with recreational doses of alprazolam, better recognized as Xanax. Anti-anxiety medications in therapeutic amounts were present as well. Evidence presented to the court indicated the prince had been battling dependencies on both alcohol and Xanax.
No Intent to Die, Coroner Concludes
Assistant Coroner Jean Harkin at Inner West London Coroner’s Court delivered a verdict of death by misadventure, finding no indication the prince meant to take his own life. The post-mortem determined that multi-drug ingestion caused cardiac arrest, which led to his death.
Harkin explained she did not believe he had intended suicide based on several factors. Reports from both treatment facilities showed no concerns, he had not expressed that he wanted to kill himself to anyone, and no note was discovered in his hotel room. CCTV evidence confirmed he was alone the night before his body was found, eliminating any possibility of third-party involvement. Harkin extended her sympathies to his family.
Private Treatment at Elite Facilities
The prince, a descendant of King Salman’s great-great-grandfather, had undergone rehabilitation at two exclusive British clinics in the months before his death. In August 2025, he entered the Priory Clinic in Roehampton, south-west London, as an inpatient. The prestigious facility charges up to £35,000 per week, and there he received care aimed at ending his reliance on alcohol, benzodiazepines and the anti-anxiety medication pregabalin.
Consultant psychiatrist Dr. Victoria Chamorro testified that the prince had reacted well to treatment, noting the detox had “proceeded without physical side effects.” In her statement, she characterized him as a patient who was supportive and kind to others around him.
When admitted, he showed signs of low mood and anxiety, Chamorro’s account revealed. Upon discharge, he was not deemed a suicide risk. He departed with a friend but failed to attend follow-up Zoom sessions, though Chamorro stated there had been no alarm about his condition and that he had responded well to treatment and completed his programme.
After leaving the Priory, he continued care at Rainford Hall clinic in St. Helens, Merseyside, where weekly treatment costs £7,000. While there, he was treated for an upper respiratory tract infection and made a full recovery, departing the facility on Oct. 14.
Final Days at a Kensington Hotel
The prince had booked a one-week stay at the £600-per-night hotel beginning Nov. 19, 2025, occupying a fifth-floor room. His last verified appearance occurred the evening before his death, when security cameras captured him going outside to smoke a cigarette before reentering the hotel by himself. The next day, a cleaner accessed his locked room and made the grim discovery.
Hotel security personnel and emergency medical responders arrived at the scene. Attempts to resuscitate him proved unsuccessful, and he was declared dead at the location.
The post-mortem examination found no acute or chronic medical conditions, determining that cardiac arrest stemming from the substance combination was responsible for his death.
Acquaintances described the prince as a discreet member of the royal family who quietly supported charitable endeavors. On December 2, the Saudi Royal Court released an official announcement confirming his death, stating he had died outside the kingdom. A funeral prayer service took place in Riyadh at the mosque named for Imam Turki bin Abdullah—a location customarily used for high-ranking figures—with a large number of princes and officials attending as a demonstration of family solidarity.
