UPPER MARLBORO, Md. — Two dozen people are stuck on a roller coaster ride at Six Flags America amusement park in Maryland, according to Prince George's County Fire Department.

Fire officials are responding as a train on the Joker's Jinx roller coaster at the park in Upper Marlboro, Md., stopped on the track Sunday, about 45 feet from the ground, said a spokesperson for Six Flags.

All 24 people on the ride are safe and not hurt, a spokesperson for Six Flags said.

It is not clear what caused the stoppage on the tracks.

Assistant Fire Chief Paul Gomez said it will probably take a few hours to get the riders off the coaster and that the car the riders are in is currently sitting upright near the top of the ride.

Six Flags' website says the ride goes 60 miles per hour and goes upside down four times.
