More than 15 people were arrested and 60 injured during the second day of Miami\'s celebration of electronic music, the Ultra Music Festival, authorities said. Lt. Ignatius Carroll of Miami Fire-Rescue said a lot of the incidents were drug-related including overdoses, but emergency responders were equipped with medications to treat those kinds of problems, The Miami Herald reported Saturday. The three-day festival, the largest in the world, attracted about 165,000 people worldwide -- if they were able to purchase $229 pre-sale tickets, which sold out within 20 seconds, the Ultra Music Festival Facebook Page said. The festival has been going on since 1999, and Carroll said there was an increase in incidents over last year. \"I didn\'t have as many calls last year as I did this year,\" Carroll said. Miami police arrested more than 15 people for possession and selling crystal meth, ecstasy and LSD, the newspaper said. Sunday was the last day of the festival.
