The man being taken away from the Sunday 102.5 Live event at Discovery Park had thrown the first punch after exchanging words with security guards near the stage.

The man was subdued and handcuffed and being led away behind a backstage fence about 90 seconds after the initial altercation when the guard who had been the target of first punch responded with a blow to the man’s face with his left hand and to the back of his head with his right.

The video was provided to News10 by an employee of the company that staged the concert who said he was troubled by the security guard’s attack.

Darryl Liner, the owner of the firm that provided security for the event, congratulated the team on his Facebook page for the overall concert security, but declined to comment when sent a link to the video of the backstage incident.

Veteran criminal defense attorney Mark Reichel said private security guards have no more police power than an average citizen and generally receive far less training than a sworn peace officer.

“This is excessive,” Reichel said after reviewing the video. “If he was law enforcement, there’s a chance he might be charged with a crime.”

The name of the disruptive concertgoer was unavailable and News10 could find no evidence that he was even arrested.

Reichel said both the security guard and his employer could be held liable if the man decides to sue.

“I would hope the security company fires this individual to make a statement,” he said.
