Was SNSD’s Jessica inappropriately touched by a man?

Not too long ago, the 12th Annual Korea-China Song Festival was held at the KBS Hall on December 2nd, for which various famous music artists from both nations came together as a way to promote friendship between the two countries.  Unfortunately, this particular event might not be remembered for creating bonds anymore.
One fancam from the festival recently caught the attention of many SNSD fans, as it contains footage of what looks like a man inappropriately touching member Jessica.
In the video, right after Jessica says the ending speech on behalf of the group, she quickly turns to Hyoyeon and seems to whisper something into her ear.  Hyoyeon then looks in the direction of the man to the right of Jessica (from the videographer’s vantage point)  in apparent shock and disgust at something, while Jessica proceeds to move to the far left where Sooyoung is standing. Meanwhile, the man on the right slowly begins to remove himself from the scene, as he walks out of sight to the right.
By the look of Jessica’s facial expression, it’s quite obvious that she was disturbed by something that happened, and the speculation over the alleged inappropriate touching has left SONES enraged.
