Machete-wielding man arrested outside Justin Bieber concert
A machete-wielding man was arrested as tens of thousands of young fans gathered for a Justin Bieber concert nearby.
According to the Telegraph, a foot-long blade was discovered as police tackled the man as fans gathered in the packed streets.
Two men were arrested after police wrestled one of the men to the floor just 500 yards from the Principality Stadium in Cardiff.
More than 40,000 young fans were expected at the singer's world tour.
"I walked past as there was lots of screaming and shouting as the police were there," a witness told The Telegraph.
"I saw a guy get arrested and the police officer hold the knife - it was massive.
"It's terrifying to think something like this could happen with so many people in town.
"It was very scary after what happened at the Ariana Grande concert."
A spokeswoman for South Wales Police said two men were arrested following a "motoring dispute".
"South Wales Police were called to a dispute involving motorists on Saunders Road, Cardiff, at approximately 3.05pm. Two men, aged 19 and 27, were arrested nearby on Penarth Road.
The 27-year-old has been arrested on suspicion of affray and the 19-year-old has been arrested on suspicion of using threatening behaviour. Both are currently in custody at Cardiff Bay Police Station, according to the Telegraph.
"There are no reports of any injuries."
