Kempf, who is from New Zealand, was at the PortAventura World theme park last month and decided to take a ride on the Shambhala roller coaster.

While on the 80-mph ride, the camera on board captured the moment Kempt caught another riders cellphone bare-handed. He returned the phone to its owner when the ride was over. 

"He couldn't believe it, he gave me a big hug," Kempf told 1NewsNow.
