A teenage neo-Nazi who created a detailed plan to attack a synagogue has been found guilty of possessing an article connected with the preparation of an act of terrorism.

Mason Reynolds, from Brighton, had also pleaded guilty to five counts of possessing material likely to be useful to a person committing or preparing an act of terrorism as well as five offences of sharing terrorist publications.

The 19-year-old had shared right-wing videos and possessed bomb instruction manuals, according to the Crown Prosecution Service.

Reynolds also had manuals on how to 3D print firearms.

He was convicted by a jury with a ten to two majority at Winchester Crown Court of the count of preparing an act of terrorism against the synagogue in Hove.

Reynolds, of Moulsecoomb Way, was arrested last June 27.

The investigation which led to his arrest was carried out by the Counter Terrorism Policing South East unit.

At Winchester Crown Court today, he was remanded in custody by the judge, Mrs Justice May, until he is sentenced on June 14.

A CPS spokeswoman said that Reynolds had “praised attacks by far-right terrorists”.

She added: “Reynolds created a note detailing a plan to attack a synagogue in Hove.

“Following a police search of his home, various devices were found which had been used to store or share material, including an iPhone and USB drives.

“He was also found to be the administrator of a Telegram channel which shared far-right extremist, anti-Semitic and racist views, as well as manuals on bomb building and how to 3D print firearms.”

Nick Price, head of the CPS counter terrorism and special crime division, said: “Mason Reynolds sought to spread hate and encourage acts of terrorism.

“Today’s guilty verdict, along with his earlier guilty pleas, show that he not only held neo-Nazi beliefs but wanted to act on them to cause pain and suffering, which fortunately has been prevented and the public protected due to the work of the policing and prosecution team.”
