A 17-year-old boy was found guilty of five terror-related charges at Birmingham Crown Court for planning an attack in Cardiff, Wales, on the same day a Justin Bieber concert was scheduled at Principality Stadium, reported The Guardian on 27 November 2017.
The boy was arrested on 30 June 2017 – a month after the concert attack in Manchester – when police raided his home for fear the plan was to be carried out on the day. The attack could have included the concert venue as the boy had done research on the event and the venue’s security. The concert went on as planned.
He will hear his sentence on 10 January 2018.
