BUENOS AIRES, Argentina—More than 100 fans were arrested after violence erupted in the stands during a Copa Sudamericana match between Independiente and Universidad de Chile and left at least 20 people injured, one of them in critical condition, local authorities said Thursday.
Images showed two fans jumping, or falling, from the upper deck of the stands to escape the attack, and another collapsed after being hit in the head with a stick. Several other fans, some in their underwear, were covered in blood and trying to evade the attackers.
