"Police are trying to extradite a suspect in the murder of a woman in central London earlier this month.
Detectives will not name the person they believe killed Angela Thiamphanit, or where they currently are.
Police found Ms Thiamphanit, 26, with stab wounds at her home in Stanhope Place, Westminster, on 8 April.
The Met Police has asked the Crown Prosecution Service to rule on whether the force has enough evidence to extradite the murder suspect.
Ms Thiamphanit, who had dual Chinese-Hong Kong and Thai nationality and worked in property management, had been living in the UK for about nine years, having initially come over to study at university."
