A high-speed motorcycle chase on the 210 Freeway ended in a dramatic crash, following the pursuit of a suspect wanted for the shooting of a San Bernardino County Sheriff's deputy in Rancho Cucamonga, as reported by NBC Los Angeles. The chase, which began shortly after the shooting incident that occurred in the 12300 block of Hollyhock Drive, led law enforcement onto the freeway ,where the motorcyclist ultimately struck the back of a car and was ejected from the bike.

The sequence of events unfolded on Monday afternoon when a Sheriff's deputy was reportedly shot at approximately 12:40 p.m.; the deputy's condition has not been disclosed according to KTLA, after which authorities spotted and engaged in pursuit of the motorcyclist, who exceeded speeds of 120 mph before the crash occurred on the freeway, and the suspect narrowly missed a collision with a California Highway Patrol motorcycle officer involved in the chase the motorcyclist had initially exited the freeway, then re-entered traveling eastbound, in the opposite direction.

Emergency responders and a Sky5 helicopter were on scene as firefighter-paramedics attended to the suspect before a medical helicopter transported them to the hospital, according to documents from NBC Los Angeles. The condition of the individual involved in the high-speed chase has yet to be reported, but vehicle and air traffic were halted in the area to provide immediate aid.

The intersection of the shooting and the subsequent chase is not yet clear, but ABC7 notes that the shooting, and the chase that ended in a significant accident on the 210 Freeway near Upland are potentially connected - the details surrounding the initial shooting, including the motive and the circumstances that precipitated the deputy's shooting, are currently under investigation, and the information will be updated as the story develops.
