Britain's Got Talent's mysterious act The Witch caused a stir during the audition process on Saturday night and viewers at home have taken to Twitter to theorise who could be behind the mask.
The "scary" contestant left fans on edge as they watched the character give Amanda Holden, 51, an apple - only to crush it up and reveal a handful of maggots and cockroaches, which prompted Alesha Dixon, 43, to flee.
After the creepy-crawly surprise The Witch, disguised behind a costume and facial prosthetics, concluded with the mysterious figure disappearing in sparks while on stage.
