A 17 year old kid was found guilty of 5 terror related charges after he was planning an Isis related attack at one of Justin's concerts in Wales.
Police found a claw hammer, a gutting knife and a suicide not in his home 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 boy claims that he wasn't planning to actually carry out the attack but just wanted to see how easy it was to research these topics online. Judging by what they found in his home, I'd say he was doing way more than just seeing how easy it was.
