British man Jermaine Grant, who was believed to be part of an extremist cell, has been handed a four-year prison sentence in Kenya for possession of bomb-making material.
The London man, who is already serving a nine-year jail term for forging immigration documents, was arrested in 2011 when police allegedly found chemicals, switches and a bomb-making manual at his Mombasa apartment.
Four years will be added to his current sentence, although the BBC reports he has denied the charge and is appealing.
Grant was convicted last month of possession of bomb-making materials, although the court acquitted him of conspiracy over the alleged plot.
Following his arrest in 2011, Kenyan police accused him of being involved in a terrorist cell which was planning attacks on Western interests in the Mombasa area over Christmas 2011.
It has also been claimed that Grant was sharing his apartment with British terrorist Samantha Lewthwaite. Also known as the “White Widow” Lewthwaite was married to Germaine Lindsay, one of the bombers who carried out the 2005 London terror attacks, that killed 52 people.
