Country singer Luke Bryan punched a spectator at last night’s Volunteer Jam at Bridgestone Arena in front of cameras.

Luke Bryan Punches a Fan

In a video posted on Twitter, a spectator in the front row of the concert gave Bryan the middle finger. Mid-song, Bryan walked to the edge of the stage, and said “Come on.” After the man raised his hands again, Bryan punched him in the face with his right hand.

A security guard, who standing on stage, then went into the crowd.

Bryan has not personally addressed the incident, but his spokesperson told ET: “A man in [the] front row was making crude hand gestures toward Luke during his performance. It was insulting not only to him, but more importantly to the men, women, and families sitting around him who were there to support and celebrate Charlie Daniels and the efforts of raising money for the military veterans — some of [whom] were in the audience. The concert security personnel saw the man’s disruptive actions of the event and he was escorted out.”
