Metallica sure knows how to rock a crowd: Nearly 170 people were arrested Wednesday night after hundreds of fans tried to break into a Metallica concert in Bogota, Colombia. Police used water cannons and tear gas to disperse rioting concertgoers. Members of the nation’s military were on standby ahead of the gig following reports that the band’s show in Santiago, Chile was marred by rioting in January. More than 1,500 officials were organized to patrol the streets around Simon Bolivar Park ahead of Wednesday’s concert. Despite the extra efforts, at least eight people were injured when hundreds of fans without tickets attempted to force their way into the sold out performance.
