Social media company Tik Tok said on Friday it was unable to find evidence of actual threats to schools on its platform that caused US administrators and law enforcement authorities to heighten security, warn parents and cancel some classes.
One of the country's largest school districts, in Florida's Palm Beach County, said in its letter to parents on Friday that local police were aware of a "video circulating on Tik Tok nationally, encouraging violence in schools."
Tik Tok said on Friday that it had been unable to find any credible threats on its platform, only "alarmist warnings" which were being removed for violating Tik Tok's misinformation policy. Palm Beach County Schools did not respond to a request for details about the alleged video.
"We continue to aggressively search for any such content on our platform, but we are deeply concerned that the proliferation of local media reports on an alleged trend that has not been found on the platform could end up inspiring real world harm," Tik Tok said in a statement.
