An inquest has determined that Prince Abdullah bin Fahad bin Abdullah bin Abdulaziz bin Musaed bin Jalawi al Saud, 29, died from cardiac arrest triggered by a fatal combination of substances following extended rehabilitation treatment at British private clinics. Staff discovered the Saudi royal’s body on the bathroom floor of his room at the Marriott Hotel in Kensington on Nov. 25, 2025.
Assistant Coroner Jean Harkin delivered a verdict of death by misadventure at Inner West London Coroner’s Court, finding no indication the prince sought to take his own life. Post-mortem examination established that multi-drug ingestion caused his cardiac arrest.
Lethal Substance Levels Found in Blood
Laboratory analysis showed the prince had consumed 222mg of alcohol per 100ml of blood—a concentration approaching triple England’s 80mg drink-drive threshold. According to testimony, such elevated levels could induce coma on their own.
Toxicology results also revealed potentially lethal quantities of gamma-hydroxybutyrate (GHB), widely known as a “party drug.” Cannabis traces appeared alongside recreational doses of alprazolam, the medication sold as Xanax, plus additional anti-anxiety pharmaceuticals at therapeutic concentrations. Evidence presented to the court indicated the royal had been struggling with alcohol and Xanax dependency.
Private Clinic Treatment Preceded Discovery
The prince underwent inpatient care at two facilities before his death. He entered the Priory Clinic in Roehampton, southwest London, during August 2025 to address dependencies on alcohol, benzodiazepines and pregabalin. Weekly treatment at the prestigious center can cost £35,000.
Consultant psychiatrist Dr. Victoria Chamorro testified that detoxification “proceeded without physical side effects.” She characterized him as supportive and kind toward fellow patients and staff. Initial assessment identified symptoms of anxiety and low mood, but by discharge he presented no suicide risk, according to medical evaluation.
A friend accompanied the prince when he left the Priory. Though he missed follow-up Zoom sessions afterward, Dr. Chamorro stated there had been no alarm since he had completed his program and responded favorably to treatment.
He subsequently received care at the Merseyside facility Rainford Hall clinic in St. Helens, where weekly private treatment runs £7,000. Medical staff treated him for an upper respiratory infection during this stay. He recovered and departed the facility on Oct. 14.
The royal, a descendant of King Salman’s great-great-grandfather, had reserved accommodation at the west London Marriott for one week starting Nov. 19, 2025, paying £600 nightly for his fifth-floor room. Security cameras recorded his final known movements the evening before staff found him, showing him stepping outdoors to smoke before re-entering the hotel unaccompanied. A housekeeper discovered him the next day inside his locked room, still fully clothed.
Hotel security and emergency medical personnel responded immediately. Resuscitation efforts proved unsuccessful, and he was declared dead at the scene.
No Suicide Intent or Outside Involvement
Post-mortem findings showed the prince suffered from no underlying acute or chronic medical conditions. His fatal cardiac arrest stemmed exclusively from the drug and alcohol mixture, according to pathology reports.
Assistant Coroner Harkin ruled he had not intended self-harm. She cited clinical records from both Rainford Hall and the Priory showing no red flags, the absence of suicidal statements to anyone, and no suicide note in his hotel room. Video surveillance definitively placed him alone the night preceding his death, eliminating third-party involvement theories. Harkin extended sympathies to his relatives.
Those acquainted with the prince remembered him as a quiet member of the royal family dedicated to philanthropy. The Saudi Royal Court released an official announcement on December 2 confirming he had died abroad. Funeral prayers took place at Riyadh’s Imam Turki bin Abdullah Mosque, a venue typically reserved for distinguished individuals, with Saudi press noting substantial attendance by princes and government officials demonstrating familial solidarity.
