According to Burbank police, three adults and three minors suffered minor injuries. Officials say five were taken to Providence Saint Joseph Medical Center, and one was taken to Providence Holy Cross Medical Center.
Burbank police initially reported that four adults and three minors were injured. That figure was later updated by the Burbank Fire Department.
The incident happened before noon. A representative from the equestrian center said two horses broke away from their riders, and then collided with other riders and people in the area.
According to "Vickie," who was one of the people injured in the group, it happened at the end of a trail ride. The group was heading back to the stable, when one horse in the back took off running. According to Vickie, the trail ride became a stampede.
"They were coming every which direction, and they were telling us pull back on the horse, but the horses were just going up in the air and everybody starting falling, and I fell," said Vickie. "All of a sudden I'm on the ground, I'm trying to curl in a ball because I didn't know if the horses were going to go over top of me."
She broke her wrist and fractured a rib. She says it was a large group, too large in her opinion. What exactly spooked the horse is unclear. Some riders say it may have been a tractor that backfired or the loud speaker coming from a rehearsal at the equestrian center.
According to other riders and witnesses who were eating lunch at a nearby restaurant, one horse was galloping down the trail, and other horses followed suit.
Witnesses say police and firefighters responded quickly to the scene.
Burbank police said the horses were eventually contained.
The Burbank Police Department was handling this situation.
