At least four people were injured and approximately two dozen others were stranded on board the Ninja Ride at Magic Mountain in Los Angeles, California, after a tree branch fell on the ride's track.

On Monday, Ninja Ride passengers were stuck 20 feet above the ground after the coaster stopped in the middle of its track and injured the four passengers seated in front of the ride. Among those hurt, one person suffered a knee injury and another suffered a neck injury, according to ABC 30.

Luckily, none of the injuries were considered to be serious and all of the victims have been sent to the hospital immediately after rescuers helped bring them down.

Several visitors at Six Flags shared photos of the incident on Twitter with one user @JulieSone who wrote, "Magic Mountain update: rescue efforts underway; all riders are alert, conscious & talking. @SCVSHERIFF @LACo_FD."

Another person shared a photo that was taken from inside one of the coasters that were stuck 20 feet above the ground and said that it was sent to her by her sister, who was awaiting rescue, the Huffington Post reported.

Park spokeswoman Sue Carpenter told various publications and news channels, "The 25 guests on the train were all alert and corresponding with park personnel during the evacuation process."

On its official website, the Ninja Ride is described as a top speed ride that travels at 55 miles per hour. "Your whole body will swing out to the sides as you take the winding snake-like turns at nearly 4G. In fact, once its warrior begins its run there's hardly any straight track at all."

Meanwhile, one YouTube user shared a surveillance video that showcased all the riders being rescued by park personnel. In the video, it can be observed that coasters look very similar to those of the old XLR8, because they were the ones shipped to Six Flags Magic Mountain when the Astroworld closed, ABC 13 has said.
