London teen who threatened prom jailed for possessing terrorist materia

Dihan Rahman, 19, owned guides on how to build bombs and also had pro-ISIS and extreme right-wing material

A teenager who threatened to “ruin prom” and had bomb-making videos and a terrorist manual has been jailed.

Dihan Rahman, 19, was sentenced to four years and six months for terrorism, stalking offences and making indecent images of children at the Old Bailey on Wednesday.

Rahman, from Southall, was found to have downloaded guides on how to build bombs and also had content related to various terrorist ideologies, including incel, pro-ISIS and extreme right-wing material.

Counter Terrorism Policing (CTP) detectives found that Rahman was the administrator of the far-right wing Strumjäger Group on encrypted messaging app Telegram and had frequently expressed antisemitic views after analysing his mobile phone and computer, including an encrypted hard drive.

The teenager had pleaded guilty to three charges of possession of documents of a kind likely to be useful to a person committing or preparing an act of terrorism, as well as stalking two teenage girls and a female teacher, in February.

Rahman was accused of stalking and threatening two teenage girls when one of the girls rejected him romantically shortly after he moved to a new school.

He then bombarded her with messages on social media, doxxed her and her friends’ details to encourage harassment online, and visited locations he knew they would be.

Rahman also posted images to social media in which he tagged the venue for the school prom alongside a photograph of a German Nazi soldier in a forest holding a gun. The event was moved for security reasons, with extra security added.

When his behaviour was reported to the school, Rahman had his phone confiscated by a teacher, who saw images of him dressed in army uniform with the words “kill yourself” and another with the caption “who’s in for a Valentines school shooting”.

There were also images of Adolf Hitler, Saddam Hussein, beheadings, dead bodies and violent images of women being hurt and strangled, and a manifesto he had written was found in his school bag.

Rahman would go on to stalk the teacher who had found the images and manifesto after the school contacted the police, and he was arrested in November 2024 after CTP detectives found that he had posted details of the girls and teacher online suggesting they were involved in a “conspiracy” in relation to the investigation into him.

He was subsequently remanded in custody and pleaded guilty to three counts of possession of Indecent Images, and three counts of stalking.

Rahman originally admitted to owning the documents but claimed he didn’t know that they contained information that would help a terrorist.

Commander Helen Flanagan, head of CTP London said: “This case is yet another example of a growing and concerning trend of young people being drawn into extremist, violent and terrorist ideologies – principally from what they are exposed to and consuming online.

“Rahman’s actions towards his victims – two of whom were teenage girls – were completely unacceptable and I want to praise their incredible courage and resilience throughout this whole ordeal. I would also like to praise the actions of Rahman’s teachers, who contacted police with their concerns, which enabled us to intervene and investigate when we did.

“With the threat level now raised to severe, everyone can play their part to keep themselves and their communities safe. If you see or hear anything that doesn’t look or feel right, then please report it to us. Your information could help us save lives.”

Bethan David, Head of Counter Terrorism for the Crown Prosecution Service, said:“Dihan Rahman was driven by his extreme ideologies and misogynistic views.

“He was an administrator of an extreme far-right group that is known for its encouragement of violence, he had material containing pro-ISIS, far-right views and depicting violence against women.

“His derogatory views about women and his interest in mixed extreme ideologies drove him to commit the stalking offences causing considerable fear and distress to his victims, who have described the effect his actions have had on them.

“Today’s sentencing reflects the seriousness of his crimes, and I hope can bring some closure to his victims, my thoughts remain with them.”
