More than 20 people are stuck mid-air on a stalled roller coaster at an amusement park outside Washington, DC.
Prince George's County Fire/EMS spokesman Mark Brady tweeted that the riders got stuck about 5.30pm on Thursday at Six Flags America in Largo, Maryland.
The Berwyn Heights volunteer fire department tweeted that the cars of Joker's Jinx are 30 metres from the ground.

Helicopter video from WJLA-TV shows six cars. Brady says the riders do not appear to be in distress. He says the department's high-angle team is developing a rescue plan.
Two dozen passengers became stuck on the same ride in August 2014. Representatives for Six Flags did not immediately return a telephone call seeking comment.
