Man jailed for sharing violent extremist content online

A man who sent terrorist propaganda to others over an instant messaging app has been jailed, following an investigation by the Met’s Counter Terrorism Command.

Ali Abdisalam Sheikh Abdillahi, 31 (02.02.91) and from north London, shared the extremist material on a channel he created on the app in July 2020. This material included recordings of an Islamist extremist preacher who advocates armed jihad, and two Daesh propaganda videos showing executions and graphic violence.

Upon being arrested, his devices were recovered and analysed, and evidence of his having sent extremist content to others was discovered.

He was sentenced to a total of eight years and ten months’ imprisonment at the Old Bailey on Monday, 14 March. He will spend an additional three years on licence and be subject to a Serious Crime Prevention Order upon his release.

Commander Richard Smith, who leads the Counter Terrorism Command, said: “The sharing of content which shows and advocates extremist violence is extremely harmful and dangerous. Abdillahi sought to radicalise others to his hate-filled ideology when he posted this material online, but counter terrorism officers arrested him and put a stop to his online activity.

“We would urge anyone who sees any kind of content online which condones and encourages terrorism to report it to police. There is a dedicated team of counter terrorism officers who get this kind of content removed from the internet, and identify offenders, and information from the public is vital.”

Abdillahi was arrested by officers on 7 August 2020. He was charged on 18 August 2020.

He admitted to five counts of disseminating a terrorist publication, contrary to section 2 of the Terrorism Act 2006, at Woolwich Crown Court on Tuesday, 16 November – the second day of his trial.

At an earlier hearing at the Old Bailey on 19 July 2021, Abdillahi also admitted to perverting the course of justice, and fraud – these charges, brought against him in June 2021, related to a fraudulent university degree certificate used to gain employment, and to unsuccessfully apply for bail for the terrorism charges.

He was sentenced to eight years’ imprisonment for the terrorism charges and a further ten months for perverting the course of justice, which will run consecutively. No further penalty was imposed for the fraud offence.
