CHARLOTTESVILLE, Va. (CBS19 NEWS) -- There were some frantic moments at Charlottesville High School on Monday, but it was all a hoax.

Police received a call saying there was an active shooter at the school.

Schools in Culpeper County, Lynchburg, and Arlington among other places all had similar calls, saying there was an active shooter in a school building.

"I’m thinking, my younger sister is in that school, what do I do? I'm texting her and calling her saying 'Stay down, stay down. It's going to be alright," said Kaiden Drumhull, a student at CHS.

Police explain that this situation is serious, even though the call proved to be false.

"We're not going to take these lightly and we're going to respond accordingly until we can assure that the safety of these kids and this community is the first and foremost important to us," said CPD Interim Chief Latroy Durrette.

As of now, there aren't any leads on a suspect, and with several schools in Virginia receiving similar threats at similar times, it could a complicated investigation.

It's not just Virginia. In Florida, there were three incidents on Friday. There were also threats in Texas, California, Oklahoma, Missouri, Kansas, and Illinois last week.

At this time, it is unknown if any of the calls were related but police will be investigating this.
