Eight rollercoaster riders were stuck upside down on a carnival ride Sunday at a Wisconsin festival.

The stoppage took place at the Forest County Festival in Crandon, which is approximately 230 miles north of Milwaukee.

The riders on the Fire Ball were stuck for at least three hours as first responders worked to bring them down safely.

"All we know that there is a mechanical failure with the ride where it became stuck in the upright position," Capt. Brennan Cook of the Crandon Fire Department told WJFW-TV.  "The ride was recently inspected by the state of Wisconsin here on site and at this time, we do not have any other information."

Fox News Digital has reached out to festival organizers and authorities for additional information.

A festival-goer posted an image on Facebook showing the riders hanging upside down, saying they had been that way for four hours. 

He said a little girl who was stuck told fire officials to rescue an older man "because he was struggling."
