Taiwanese rapper furious about butt getting groped by audience during performance

Some fans have a tendency to go overboard when showing their affection for their idol.
Recently, Taiwanese rapper GorDoN was performing at the Shan Cheng Music Festival when he was molested by someone in the audience. 
A man, who was standing below the stage, had reached up to squeeze GorDoN’s butt cheeks. 
GorDoN later noted that the man was standing right where the performers exit the stage, and suspects that he might be part of the crew or one of the other acts that night.
“I don’t know this person at all, he didn’t get my consent before touching me when I was on stage. This is sexual harassment. I find it very disgusting,” said GorDoN.
He added that he hopes the musical festival would not be ruined by that one bad apple, and that he wishes “no one else will ever have to experience this.”
GorDoN’s management, KAO!INC, has since told the media that they’re investigating the matter.
“We’ve asked the organisers to look into it and to look for relevant evidence. Some of the staff also saw what happened from backstage, and we’ll ask our lawyer to take legal action,” they asserted.
Though the identity of the culprit has not be confirmed, GorDoN took to his social media share that the perpetuator is indeed “that person” that everyone is speculating about.
