THIS is the terrifying moment a teenager beats up an usher at a concert after he was asked to sit in his correct seat.
Footage shows the 14-year-old boy battering the 66-year-old at an NBA Youngboy concert in Kansas before shocked onlookers drag him away.

The teen, who has not been named because of his age, was arrested on Sunday, shortly after the alleged attack.
He was later charged with two counts of assault – one felony and one misdemeanor.
Horrifying footage shows the moment Schlange tells the teen his ticket doesn’t match his seat assignment.
Minutes later, he is thrown to the ground as the boy launches his brutal onslaught.
The lad then appears to repeatedly punch the man before being dragged away by a fellow concert-goer.
Robert Daniel, who recorded the video, said the teen was asked to move elsewhere at which point, he “completely lost it”.
Schlange said he was left with serious “blows to his head” after being “repeatedly punched” by the boy.
The teenager became “so enraged”, he said.
He told Fox news: “I mean, it is serious; I went down and had blows to my head.
“Just getting him off, getting him off of me…because he was so enraged, so we were just, in essence, trying to protect the fans.”
Schlange added he remains emotionally shaken and can’t recall much of what happened.
His grandson, Herber Lopez, has since started a GoFund me page, which has amassed over $13,000 in donations.
The funds will help support his grandad who, he said, won’t be able to work after suffering damage to his eyes from the battering.
Lopez added he “won’t be able to work” and has glaucoma in one of his eyes.
The post read: “My name is Herber Lopez. We are asking for help for the physical damage my grandfather Thomas Schlange for the physical bodily damage he suffered at a concert at T-Mobile center on Sunday 9/21.
“He was attacked by a young guest, after being asked to sit at his own seat, while being in the wrong one.
“He won’t be able to work, he also have glaucoma and one of his eyes may suffer more damage later on.
“We are devastated for the injustice of this person and other attendees that didn’t stop that guy at all.
“Anything will help. God bless you.”
