Fire officials reported Thursday evening that over a dozen people were stuck 100 feet up in the air on a roller coaster at Six Flags America outside of Washington D.C.
Prince George's County Fire/EMS spokesman Mark Brady said on his Twitter account that 20 riders came to a standstill around 5:30 p.m. at the theme park in Largo, Maryland.
According to fire officials the riders are upright and no one appears to be in distress.
Six Flags' website describes the Joker's Jinx as having a "spaghetti bowl" design, with the roller coaster doing "a cobra roll, a sidewinder loop, a corkscrew, and countless swift reversals."
Six Flags America said in a statement: "Joker's Jinx did not complete its regular ride cycle, causing it to stop at a safe location on the track. The Prince George's County Fire Department is onsite to assist in getting the riders safely off the ride. The safety of our guests is our highest priority and the ride will be closed for a thorough inspection before reopening."
Two dozen passengers became stuck, some for as long as five hours, on the same ride in August 2014.
