LAS VEGAS (KLAS) — Police responded to a crash on the valley’s west side involving a motorcycle. Police originally said this was a hit-and-run, but after reviewing video and talking to witnesses concluded there was not another vehicle involved.

Police now say the motorcycle rider was a juvenile going west on Alta before Fox Hill Dr. when the rider veered left, hit the median, and was ejected into a tree. The rider was flown by helicopter to UMC Trauma in critical condition.

Police say the rider was on a 2007 Harley Davidson Night Rod. Police have not released the rider’s age and will not release their name because of their age.
