In February 2012, anti-terrorist police in Nairobi, Kenya, issued an arrest warrant for a white woman using the false name of Natalie Faye. The white woman was known to have used a fraudulently obtained South African passport. After liaising with Scotland Yard, they said that the woman was known to be using at least three separate identities that included her true identity, Samantha Lewthwaite, and was accompanied by three children. The woman was wanted in connection with links to an Al-Shabaab terrorist cell planning attacks in Kenya in reprisal for anti-terrorism operations being conducted in Somalia. The photograph of the woman in the passport bore "a strong likeness to Samantha Lewthwaite." The police said: "We believe she is not a small fish. She is among several Britons that our intelligence service is aware of in relation to terrorists' plans to attack us." The woman had entered Kenya in November 2011 using the passport and then joined other members of the cell in Mombasa. The real Natalie Webb was discovered to be an English nurse living in the home counties who had been the victim of identity theft. A "large team" of detectives from SO15, the Metropolitan Police Service's Counter Terrorism Command, travelled to Nairobi to assist with the investigation and attempts were launched to locate Lewthwaite in Britain.
