The man, who said he was celebrating his niece’s birthday at Castles N’ Coasters in Phoenix, told NBC affiliate KPNX he was riding Desert Storm, a double-looping roller coaster, when his lap bar unlatched just seconds after the ride began.

Video captures the moment a man says he realized his lap bar unlocked during a roller coaster ride at an Arizona amusement park. The man jumped off the ride to safety. CNN affiliate KPHO with the reports says they have tried to contact Castles N’ Coasters,
