LAS VEGAS (KLAS) — A chaotic scene inside a Las Vegas trampoline park, Spy Ninjas HQ, was captured on video.

On Saturday, Feb. 7, Knox and his family were celebrating his 10th birthday. The video shows the child about to ride the zip line. Knox, seen harnessed, appears to jump off the platform, make it through a portion of the obstacle, before falling.

His family told 8 News Now, he fell more than 20 feet to the ground.

“They didn’t have any cushion on the floor. It was pretty much straight concrete,” said Knox’s uncle, Navonte Hill. “He landed straight on his back and his head.”

They say they cannot watch the video anymore as it’s “traumatizing.”

“Definitely the scariest moment as a family, for all of us,” Hill said. “You know, on his birthday on top of it!”

According to the family, the child suffered from a concussion but is recovering. Hill said the family is spending as much time as possible with Knox, and he is expected to return to school soon.

Spy Ninjas, located near Buffalo Drive and Sahara Avenue, has remained open since the incident.

8 News Now reached out to Spy Ninjas, as well as their founders, YouTube Stars Chad Wild Clay and Vy Qwaint , for comment and is awaiting a response.
