MUSLIM convert dubbed 'Jihadi Jack' has reportedly been spotted on TV in a Syrian jail.

Jack Letts was 18 when he left his Oxford home to join the Islamic State terror group in Syria in 2014.

Letts, who held dual UK-Canadian nationality, was jailed after Kurdish forces captured him as he tried to flee to Turkey in May 2017.

He is now reportedly being held with dozens of other prisoners in a Syrian jail which featured on the US network CBS last week.

Letts appeared to be seen lying on the floor wearing an orange jumpsuit surrounded by other prisoners.

The 24 year old, who has been stripped of his UK citizenship after travelling to the Middle East to join Islamic State, was reportedly identified by his parents.

His mother Sally Lane told The Mail On Sunday: "It's worse than my worst nightmares."

She added: "If there is evidence he has committed a crime, then bring him home and put him on trial, and if he is guilty, send him to prison. 

"But he has been in this limbo for two-and-a-half years with no end in sight."

Letts was stripped of his UK citizenship in August and a Home Office spokesman said "This power is one way we can counter the terrorist threat posed by some of the most dangerous individuals and keep our country safe".

The Canadian government responded by saying it was "disappointed that the United Kingdom has taken this unilateral action to offload their responsibilities".

In an interview with ITV earlier this year, Letts said he felt British and that he wanted to return to the UK, but admitted he did not think that would be likely.

He said: "I’m not going to say I’m innocent. I’m not innocent. I deserve what comes to me. But I just want it to be… appropriate… not just haphazard, freestyle punishment in Syria."

Letts converted to Islam at the age of 16. He used to attend the Bengali mosque in Cowley Road, Oxford, before he came into contact with men with a more radical ideology.

His parents, John Letts, 58, who also has dual British and Canadian citizenship, and his mother, Sally Lane, 57, were convicted at the Old Bailey of one charge of funding terrorism in September 2015.

The pair sent Jack £223 but avoided jail after being sentenced to 15 months imprisonment suspended for 12 months.
