On Thursday night, the Southeast Delco School District decided to cancel classes amid the Tiktok rumors sweeping the country.
"I'm glad they're doing the precautions. It's just frustrating because this is the third time they're doing some type of threat," said Ashley McGriff of Sharon Hill, Pa.
McGriff has a second and fourth-grader in the district. She says even if classes were held, she likely wouldn't have sent them.
A Southeast Delco school statement said police are investigating the issues that led to the closure.
