Interpol have issued a warrant for the arrest of Northern Irish woman Samantha Lewthwaite at the request of Kenya. The agency issued a Red Notice, or internationally wanted persons alert, following the massacre at a shopping mall in Nairobi.

The 29-year-old from Banbridge in Co. Down is wanted by Kenya on charges of being in possession of explosives and conspiracy to commit a crime dating back to December 2011.

Circulated to all 190 Interpol member countries, the Red Notice represents one of the agency's most powerful tools in tracking international fugitives.

Lewthwaite now tops the Interpol website

"By requesting an Interpol Red Notice, Kenya has activated a global ‘tripwire’ for this fugitive," said Interpol Secretary-General Ronald K. Noble.

"Through the Interpol Red Notice, Kenyan authorities have ensured that all 190 member countries are aware of the danger posed by this woman, not just across the region but also worldwide," he added.

Lewthwaite is also believed to use the alias 'Natalie Webb'.

Mr. Noble said the publication of the Red Notice for her meant that the public could also play a crucial role in providing information to law enforcement to help identify and locate her.

Lewthwaite is the widow of Germaine Lindsay, one of the four bombers involved in the July 7th terror attacks in London in 2005, in which 52 people were killed and hundreds more injured.

It has now emerged that Ms. Lewthwaite gained a South African passport using a fake identity. South African Home Affairs Minister is Naledi Pandor.
