The psychological illusionist was filmed scaring theme park staff with a four-legged demon on a leash.
The stunt, which was part of a promotion for Brown's upcoming ghost train ride at Thorpe Park in Surrey, saw unsuspecting staff members running in terror as the creature lunged at them.
In one scene the demon, which was actually a man wearing an extremely impressive costume, managed to scare the living daylights out of a woman at the park's ticket office while in another it was able to surprise an attendant who had been picking up litter.
Towards the end of the video the four-legged nasty terrified a women exiting an elevator at the company's offices before riding it to the upper floor and chasing the staff down the corridors.
"I am excited to reveal another glimpse into my new attraction, giving the first look behind the doors of the Ghost Train," said Brown.
"Over the last few weeks I have been testing out the components of the attraction and decided to run scare tests with my demon creature - the reactions were hilarious and very encouraging."
