Teenager arrested aged 16 jailed after terror conviction
Yusuf Shah was 16 when he was stopped at Heathrow Airport in 2024
A teenager who was 16 when he was arrested at Heathrow Airport has been jailed after being convicted of providing cyber-security support to groups including al-Qaeda.
Yusuf Shah, from Ilford, was also found to have downloaded documents including instructions on how to make explosives and how to use different types of weapons.
Analysis of Shah's phone found that he had accessed an online magazine published by al-Qaeda that contained information on how to carry out acts of terrorism, and had engaged in chat groups where he offered technical help.
Cdr Helen Flanagan, head of Counter Terrorism Policing London, said the case should act as a "warning to parents and carers to be aware of what their children are doing online".
Shah, who was stopped at Heathrow Airport in London under schedule 7 of the Terrorism Act in January 2024, was convicted at Kingston Crown Court and sentenced to four years and two months in prison.
Cdr Flanagan said the police investigation found Shah was being drawn into extremist material and ideologies "when he was only 13 or 14 years old".
She added: "This is reflective of a growing trend of young people being radicalised and accessing extremely dangerous and violent terrorist ideologies and material online."
Shah, who is now 18, had downloaded documents providing instructions on the use of different types of weapons, the Metropolitan Police said.
He had also engaged in chat groups that supported terrorist groups, on the messaging app Telegram.
