An overzealous fan was arrested at the weekend (ends23Jul16) after touching Justin Timberlake's neck at a golf tournament in California.

The Cry Me A River singer was one of the competitors at the American Century Celebrity Pro-Am in Lake Tahoe, and while walking through a group of spectators, he was unexpectedly touched by an attendee, who reached out his hand and patted the right side of Timberlake's neck.

In the video footage obtained by TMZ.com, the clearly frustrated singer, who was flanked by two security guards, turned around and yelled at the man, "Why would you do that?" Timberlake then stormed off as security guards at the event confronted the unnamed man.

Representatives for the tournament tell TMZ the confrontation was minor and Timberlake, who did not have any visible injuries, did not want to press charges.

Law enforcement officials say the spectator appeared to be intoxicated and became belligerent, claiming he only wanted to "touch" the pop star.

Police later attempted to escort him off the course but they eventually arrested him for disorderly conduct, according to TMZ.
