Several people were hurt while riding a roller coaster at Six Flags Great Adventure in New Jersey on Thursday.

It happened around 7:30 p.m. after some kind of malfunction on the "El Toro" ride.

Firefighters say five people were taken to a local hospital with minor injuries, and the park says several guests reported back pain.

The ride has been closed for inspection.

In a statement, Six Flags said: 

Several guests reported back pain and minor injuries after riding El Toro last evening. Thirteen guests were evaluated at the park, of which five were taken to a local medical facility for evaluation, where they were treated and released. 

The ride completed its normal cycle and all guests exited the ride without need of assistance. The ride will remain closed for inspection. Any maintenance and repairs necessary will be completed and the ride will be re-inspected by our engineers, maintenance professionals, our 3rd party independent safety inspectors and the state of NJ prior to re-opening.
