Speculation had been rife linking Ms Lewthwaite, who spent part of childhood in Northern Ireland, with the grouping responsible for storming the Westgate centre in Nairobi.
More than 70 people died, including 61 civilians, six security forces and five al Qaida-linked militants, in the armed assault which unfolded between 21 and 24 September.
Police have now identified four of up to six armed men, a figure revised down from 10 to 15 as previously thought, who carried out the siege - and said "there was no woman" involved.
Interpol recently released a Red Alert looking for 29-year-old Ms Lewthwaite, who was married to one of the 7 July bombers and is known as the 'white widow'.
She is wanted by authorities in Kenya on charges of being in possession of explosives and conspiracy to commit a crime dating back to December 2011.
Ms Lewthwaite spent part of her childhood in Banbridge and her mother's side of the family hail from the Co Down market town.
The alert has been circulated to all 190 Interpol member countries.
