CHARLOTTE, N.C. (AP) — A power outage has stranded visitors on at least three rides at a North Carolina amusement park.

Multiple media outlets report that power went out briefly Thursday evening at Carowinds theme park on the border of North and South Carolina near Charlotte.

Photos posted online show riders dangling high in the air on a rotating swing ride called the WindSeeker. The Carowinds website lists the tower as 301 feet tall. The Charlotte Observer (http://bit.ly/1tfieQB) reports that park staff were manually lowering the ride about an hour and 40 minutes after it got stuck.

Other riders stuck on two roller coasters were rescued more quickly, media report. No injuries were reported.

The cause of the outage wasn’t known Thursday night.
