Authorities Sunday continued to investigate the crash of a tram at Universal Studios that injured 15 passengers.

Paramedics dispatched to the location at 9:05 p.m. Saturday transported 15 people to a hospital, a Los Angeles County Fire Department dispatcher told City News Service. The conditions of the victims were not immediately clear, though most were believed to have minor injuries.

“There was a tram incident at the theme park … that resulted in multiple minor injuries,” a Universal Studios Hollywood spokesperson told The Hollywood Reporter. “We are working to support our guests and to understand the circumstances that led to the accident.”

The Los Angeles County Sheriff’s Department and California Highway Patrol also responded to the scene.

“Deputies responded to the lower parking lot of Universal Studios Hollywood regarding a tour tram collision,” the Sheriff’s Information Bureau said. “The collision caused several passengers to fall out of the vehicle. LA County Fire treated people on-scene and several were transported via ambulance to a local hospital with non-life-threatening injuries.

“California Highway Patrol also responded to the location to take a collision report. The cause of the accident is still under investigation and there is no further information at this time.”

CHP Officer Sergio Garcia said the initial report indicated that the tram overturned.

The tram tour is one of the most popular attractions at the Universal City theme park, featuring a one-hour behind-the-scenes look at the backlot where some of Hollywood’s most famous television shows and movies were filmed.

Starting Friday and continuing through Aug. 11, the tour is set to add several temporary attractions including immersive photo ops, throwback tram cars and an original replica of the Hollywood sign as part of its 60th anniversary celebration.

It was unclear whether Saturday’s accident would alter those plans.
