A British terror suspect linked to the notorious White Widow Samantha Lewthwaite has been returned to the UK from Kenya after serving a lengthy jail term in the African nation for possessing bomb-making materials and forgery.

Jermaine Grant was flown back to Britain on Thursday accompanied by Kenyan officials and immediately arrested upon his return.

A Kenyan court last year ordered Grant to be deported once his prison sentence had elapsed following a case made by prosecutors for him to be kicked out.

Investigators have linked him to Samantha Lewthwaite, the wife of 7/7 terrorist bomber Germaine Lindsay. 

Grant was apprehended by the authorities trying to cross into Somalia while reportedly disguised as a woman in a burka after they found bomb-making materials in his flat.

Security sources warn Samantha Lewthwaite may be hiding alongside jihadist-sympathisers in Yemen following her split from her partner of seven years

He was then sentenced to four years in prison in 2019, to be served alongside a separate nine-year sentence for forgery.

A government spokesperson told MailOnline: ‘We can confirm that an individual was deported to the UK following the completion of a criminal sentence in Kenya.

‘Our priority remains to ensure the safety and security of the UK. 

‘We will continue to do whatever is necessary to protect the UK and have one of the most robust counter-terrorism frameworks in the world to ensure this.’

Grant, a Muslim convert, was arrested by Kenyan police in a flat in Mombasa in December 2011. They believed he had been planning a bombing campaign against hotels popular with foreign tourists.

Investigators found chemicals, switches and a manual on explosives in the apartment, which he is believed to have shared with Lewthwaite, known as the White Widow.

When police swooped on Grant’s flat Lewthwaite had fled, escaping just minutes earlier after Grant allegedly warned her with a text message.

It read: ‘The lions are inside. One of them is very watchful, like a bird watches a stone.’ 

Lewthwaite remains at large as one of the world’s most wanted people and has not been seen since – though security sources believe she fled Somalia after leaving her fourth husband two years ago.

She is suspected of orchestrating a string of terror attacks in Africa that have killed more than 400 people including the  deadly 2013 shopping centre attack at the Westgate in Nairobi that killed more than 60 civilians and several soldiers.

Lewthwaite remains on Interpol’s red notice list – the de facto ‘most wanted’ list of international terrorists and criminals. 

‘White Widow’ Sam Lewthwaite, the world’s most wanted woman

Samantha Lewthwaite, originally of Aylesbury, Buckinghamshire, was the wife of 7/7 bomber Germaine Lindsay and is thought to be behind scores of suicide attacks across Africa and the Middle East.

Interpol issued a Red Notice warrant for her arrest after she was linked to the 2013 Westgate Mall attack in Kenya, which left five Britons and 66 other people dead and injured around 200 others.

Security services believe her other atrocities include the slaughter of 148 people by gunmen at a university in 2015.

In Yemen, she is understood to have recruited female suicide bombers with bribes of £3,000. She is also thought to have sent male suicide bombers as young as 15, high on heroin, to their deaths.

London University graduate Lewthwaite reportedly altered her appearance through plastic surgery and piled on weight in a bid to remain unrecognised.

She has pledged to raise all of her four children, who have three different fathers, as jihadists.  

As a teenager she was seduced by the teachings of extremist cleric Trevor Forrest, or Sheikh Abdullah el-Faisal, through whom she met Lindsay, who killed himself and 26 others in 2005.
