reported that everyone's favourite shady organisation could be behind the craze, after a conspiracy blog claimed that the clowns are a trigger for mind control.
Apparently, we've all been unknowingly pre-programmed to carry out a mission for the Illuminati, and scary clowns are the symbol which will kick us into action.
Some have claimed that the Illuminati is behind the killer clown trend Credit: Getty Images It's just a Hollywood publicity stunt The upcoming remake of Stephen King's clown-based horror novel It would be the perfect excuse for a worldwide publicity stunt by the film's producers.
However, after this claim was levelled at New Line Cinema, the producers were forced to deny it, claiming they have nothing to do with the sinister trend.
And Stephen King himself even had to come forward to deny any involvement in the creepy clown craze, insisting he's not to be blamed either.
Even if he wasn't directly involved, copycat clowns could have been inspired by the clown in It , and started a trend which quickly spiralled out of control.

The so-called 'Wasco clown' started the trend by dressing up as a creepy clown and posting shots on social media as part of a perfectly innocent photography project.
But things got a bit out of hand when locals saw his clown photos online and decided to join in themselves, venturing outside to terrorise people behind the cover of a clown mask.
Perhaps the recent surge started with a similar project, before being taken too far by copyclowns?

A killer clown dressed as the Maccies mascot caused a panic after stalking a branch of the popular fast food outlet.
And some people claim Ronald is to blame for the whole thing, with a conspiracy blog describing him as a satanic symbol.
Social media is the culprit Perhaps the best theory behind the killer clown craze is the simplest: the popularity of clown videos on social media means viewers have joined in to get online recognition.
This means that any of the above theories could be blamed for the trend's origin, whilst social media could be responsible for encouraging the copycat clowns who have joined in since.
