The former right-hand man of infamous hate preacher Anjem Choudary (pictured) has been allowed to return from fighting in Syria to work in the UK, despite being deemed “a risk to the national security”.

The jihadist, identified by the pseudonym Abu Rayah, went to fight in Syria just three years ago but is now delivering take away food to unsuspecting members of the public in London.

Mr. Rayah, who now works for Just Eat, has previously hit the headlines when he was fronting the Muslims Against Crusades group, whose members celebrated the 9/11 terror attacks and burnt poppies on Armistice Day.

He travelled to Turkey in 2014 under the guise of a “two-week family holiday” before entering Syria for up to four months.

According to the Daily Mail, authorities deemed him likely to have engaged in “terrorism-related activity likely including fighting” there, but he was able to travel back freely through Europe on his return.

In the end, he was deported back to the UK from Bulgaria on suspected terror offences.

Speaking outside his council flat in East London, he told the Daily Mail: “I haven’t had my passport removed. I don’t know what you’re talking about. I don’t want to know.”

Previously, in March 2015, the Home Office cancelled his passport on the basis that his activities posed “a risk to the national security of the UK”. He fought the ruling in the High Court and lost.

A summary of the Home Office’s case against him revealed the decision to remove his passport was based on continued involvement with terror groups and Islamic extremists.

Just Eat did not comment, but said it did not employ drivers directly.

Just days ago, it was revealed that security services have identified 350 Islamic State militants who have returned to Britain from Syria and continue to pose a terror threat.

Additionally, there are 3,000 violent Islamist extremists that MI5 has confirmed are already in the country, Whitehall sources suggested.
