Over 160 heavy metal fans were arrested, at least eight injured, at a Metallica concert in Bogota, Colombia last night following a riot outside of the show.
Despite capacity for 30,000 fans, the concert sold out quickly and police had placed 1,500 officers around the venue. According to reports, fans without tickets were posting messages on Facebook inciting others to riot.
"Those people that did not get in wanted to get in by force," said Ruben Castillo, a local police chief.
"The presence of police and riot teams was necessary because these misfits - there's no other name for them - damaged some windows in the surrounding area."
The concert went ahead inside the venue as planned.
