Two teenagers took a 30 minute joyride on a Blackpool rollercoaster after scaling the locked gates of the amusement park at 4am.
The thrill-seekers' ride of choice was the 82-year-old Blue Flyer, a wooden rollercoaster which can reach top speeds of 15mph at Blackpool Pleasure Beach.
After being caught on CCTV using the children's ride, the pair went into the T Cafe where they were found by security guards.
Following the thrill-seeking joyride, a 15-year-old boy was arrested on suspicion of burglary and will be dealt with by community resolution.
Lancashire Police are working to identify the other teenager.
