Detective Chief Superintendent Martin Snowden, Head of Counter Terrorism Policing North East, said: “Terrorism takes many forms. Whilst the brothers offences were not themselves acts of violence towards others, they show their concerning mind-set and aspiration to encourage others to share their beliefs.
“The publications, documents and digital content recovered from Ali’s devices featured praise for violence and support for Daesh.
“Shehzad and Ali’s dissemination of video content shows not only their own deeply radicalised mind set, but that they were encouraging support for violent radical terrorism.
“All terrorist groups rely heavily on their propaganda being shared online where it is used encourage support for their extreme and dangerous views and actions.
“Tackling all forms of extremist material is an essential part of protecting the public, safeguarding those who may be vulnerable to dangerous influences and preventing offences that incite or encourage acts of terrorism.
“The issue of online radicalisation is a serious one, but it is one that the public can really help us with. I would urge anyone who sees anything online that is concerning, to report it."
