Teen found guilty of planning terror attack at Justin Bieber concert

A 17-year-old school boy has been found guilty of plotting a terror attack in Cardiff, Wales, on the same day as a Justin Bieber concert.

A kitchen knife, hammer and suicide letter were found in his backpack. He was arrested on June 30 when the Canadian pop megastar was due to play at the Welsh capital. The court heard the boy today and found him guilty of plotting an Isis-inspired terror attack.

When police raided the boy's house, they found a claw hammer and a gutting knife in his school backpack, as well as a suicide note that read, “I am a soldier of the Islamic State. I have attacked Cardiff today because your government keep on bombing targets in Syria and Iraq. There will be more attacks in the future,” The Guardian reported.

The teenager denied that he was intending to act, insisting to the court that he didn’t believe in Islam but instead had a ‘stupid interest in the gory’ and ‘never thought about actually carrying out an attack’.

However, a jury found him guilty of all charges at Birmingham Crown Court following a two-week trial. He will be sentenced at the same court on January 10 next year.
