US schools are on high alert over a 'school shooting' TikTok challenge ...

Schools across the US will close on Friday in case a  school shooting TikTok challenge turns out to be real. 

Schools and entire districts in California, Missouri, Texas and Minnesota have cancelled classes for the day, while others who will remain open have announced that they will add extra police officers on campus and will remain on high alert. 

However, officials and police have assured parents and students that they have found scant evidence of any credible threats.

The origin of the purported TikTok challenge is not clear, though multiple videos on the app reference 'December 17' and school shootings.

'Prepared to hopefully not get shot tomorrow at school,' one TikTok user wrote on their video. 'Basically there was school threats tomorrow, Friday (December 17th) for most schools.' 

In a statement Thursday afternoon, TikTok said it was working with law enforcement to look into 'warnings about potential violence at schools,' but that it didn't determine the threats to originate or spread on TikTok.
