A machete-wielding man has been arrested at a Justin Bieber concert in the UK.
One witness told The Guardian the man was shouting he would "chop all Muslims up" outside the Principality Stadium in Cardiff.
Tens of thousands of young fans were gathered for the event and footage of police tackling the man is being shared on social media.
"I walked past as there was lots of screaming and shouting as the police were there," one witness told media.
"It was very scary after what happened at the Ariana Grande concert."
Another described the suspect as holding a "massive" blade.
Police say a 27-year-old has been arrested on suspicion of affray and a 19-year-old has been arrested on suspicion of using threatening behaviour, describing the incident as a "motoring dispute".
There are no reports of any injuries.
