Kenyan police are seeking a terrorism suspect who has used identities including, it is believed, a widow of one of the 7/7 London suicide bombers. The investigation is focused on a woman whose passport picture bears a strong likeness to Samantha Lewthwaite, widow of Germaine Lindsay. The Metropolitan Police in London and the Foreign Office are not commenting. But officials in both countries have not yet been able to rule out that the suspect and Ms Lewthwaite are the same. Kenya's police commissioner, Matthew Iteere, told the BBC that police investigating alleged terror plots raided a home in Mombasa in late December, looking for a woman called Natalie Faye Webb. The name is thought to belong to another woman who was the victim of an identity theft. The woman was not in the house, but officers recovered property and placed her on a watch list. According to the Kenyan police, the white woman has three children and entered the country on a South African passport in January 2011 and may have already left. However, there are questions about the woman's true identity because of her remarkably strong likeness to Ms Lewthwaite and the fact that she has three children. Mr Iteere said the police were not aware if Natalie Faye Webb was Samantha Lewthwaite, but were co-operating with the Metropolitan Police.
