CHARLOTTE, N.C. - Several witnesses have told NBC Charlotte that a popular roller coaster in the Carowinds amusement park was stuck for nearly 30 minutes.

The roller coaster, the Intimidator, required on-scene assistance and was reportedly shut down following the ordeal.

Carowinds crews reportedly had to come open the lap belts manually and let the stranded riders off down a set of maintenance stairs.

No injuries were reported, and officials have not released any information as to the cause of the shut down at this point.

According to witnesses, the crew was performing tests on the ride later in the day.

The park's website lists the Intimidator coaster at 232 ft fall and over 5,300 ft long. It also travels at speeds up to 80 mph, making it one of the the fastest, tallest, and longest rollercoaster in the southeast region.
