A priest has called the 'Charlie Charlie Challenge' "demonic activity", in an open letter warning his students against taking it.
ather Stephen McCarthy, who lives in Philadelphia in America has told pupils that there is no way of knowing what could happen if they take the challenge.
The Belfast Telegraph reports that Father McCarthy warned, there is no such thing as 'innocently playing with demons'.
The 'Charlie Charlie Challenge' trended on Twitter yesterday, as videos were posted of users taking the challenge, using a rudimentary form of a Ouija board.
