Westminster stabbing kills 27-year-old Kamonnan Thiamphanit, also known as Angela

A murder charge was finally brought in the Westminster stabbing of Kamonnan Thiamphanit, also known as Angela, after police extradited 18-year-old Enzo Bettamio from the United Arab Emirates and flew him back to the UK. Bettamio was charged after landing in Britain, and he was due to appear at Westminster Magistrates’ Court on Saturday, 25 April 2026.

Thiamphanit was 27 when she died. She was a Thai woman with dual Chinese-Hong Kong and Thai nationality who had lived in the UK for about nine years, having first come to study at university before later working in property management. Friends and family knew her as Angela, and her killing drew attention not only because of the violence of the case but because she was found dead in the Bayswater home she had been renting as an Airbnb, near Hyde Park. Her family said they were “unspeakably hurt” by her loss.

The investigation began after friends raised concerns for her welfare on the evening of Sunday, 7 April 2024. Police later forced entry to the Stanhope Place address at around 8.30am the next morning and found her with multiple stab wounds. Detectives said early on that they believed the attacker was known to Thiamphanit, not a stranger, and the Metropolitan Police referred itself to the Independent Office for Police Conduct after reviewing how officers responded to the welfare calls.

The case then became an international pursuit. By April 2024, detectives said a named suspect had fled the UK, and officers began working with the Crown Prosecution Service on whether there was enough evidence to extradite that person from outside Britain. The process took time because investigators had to build the case, trace the suspect overseas and work through extradition steps with specialist lawyers. On 24 April 2026, police said they had successfully extradited Bettamio from Dubai on a flight to the UK, and the next day he was charged. Detective Chief Inspector Alison Foxwell thanked Angela’s family and friends for their “patience and unwavering support,” while saying the investigation had been “incredibly difficult and distressing” for them.
