Schoolboy guilty of plotting Cardiff terror attack

A schoolboy who threatened to carry out an Islamic State-inspired vehicle attack on the day of a Justin Bieber concert has been found guilty of five terror offences.

The 17-year-old, who cannot be named because of his age, was arrested in June after searching the internet for details of security at the Canadian star's world tour show in Cardiff.

The boy, who hid a hammer and knife in his school bag and wrote a "martyrdom letter" after being radicalised online, was convicted of preparing for terrorist acts following a nine-day trial at Birmingham Crown Court.

Jurors unanimously convicted the teenager, from Rhondda Cynon Taf, of two counts of encouraging terrorism by posting extremist material on Instagram, and two charges of possessing Isis propaganda magazines.

The youth, of a white British background, was arrested at his home by police on June 30 - several hours before Bieber took to the stage at Cardiff's Principality Stadium.

At the start of the boy's trial it emerged that he had written a note apparently aimed for distribution after his death reading: "I am a soldier of the Islamic State and I have attacked Cardiff today because your government keep on bombing targets in Syria and Iraq.

"There will be more attacks in the future."
