Police tackle knifeman near Bieber show venue

A machete-wielding man allegedly shouted he would “chop all Muslims up” as he was arrested close to the venue of a Justin Bieber concert, according to witnesses.

The man seen brandishing a knife was in dispute with a taxi driver as tens of thousands of Bieber fans gathered in Cardiff city centre.

Two men were arrested as footage emerged of police wrestling one of the men to the floor just 500 yards from the Principality Stadium in Cardiff where the concert was being held. They were taken into police custody.
