In an odd encounter at a golf tournament, a fan wound up being arrested after he reached out and grabbed or slapped Justin Timberlake as the pop singer walked by. TMZ.com posted video of the incident, which took place Saturday at the American Century Celebrity Pro-Am in Lake Tahoe.

In the clip, the fan appears to reach across a security barrier, touching Timberlake’s face and neck and prompting Timberlake to stop and briefly confront the man. Timberlake can be heard saying, “Why would you do that?”

Moments later, tournament security staffers chatted with the man and appeared to order him to leave.

“Tournament reps saw it as a minor incident, and Justin — who didn’t have a mark on him — didn’t want to press charges … but when Sheriff’s deputies attempted to escort the man off the course things went south,” TMZ reports. “Law enforcement sources tell us he claimed he just wanted to ‘touch’ Justin and got overzealous — but refused to leave the premises. We’re told he appeared intoxicated and became belligerent. Cops arrested him for disorderly conduct.”
