York County is the latest division to see social media threats of clowns stopping by their schools.
York-Poquoson Sheriff's Office Lt. Dennis Ivey said they were made aware of the posts Tuesday. The posts, made on Facebook, said clowns would make an appearance in Williamsburg and all York County high schools and middle schools to "follow" people, Ivey said.
The Williamsburg-James City County schools were not specifically targeted, he said.
The Sheriff's Office posted on its Facebook page about the potential clown visits, but Ivey said that was just precautionary. The post said there is no evidence of a credible threat.
"This was just a proactive post for parents to watch their kids on social media," Ivey said.
Ivey said no one has reported an actual clown sighting yet.
The Sheriff's Office increased patrols at York County schools Tuesday, Ivey said.
The creepy clowns were first reported in South Carolina in late August, and from there the claims spread across the country. A sighting in Pennsylvania this week was linked to the fatal stabbing of a 16-year-old, according to the Associated Press.
On Sunday, a 13-year-old Hampton teen was arrested after asking a clown account on social media to kill one of her teachers at Davis Middle School.
Late last week, Hampton and Newport News schools were threatened with clown appearances in posts on Instagram, prompting increased police patrols.
Hampton police Lt. Jason Price said investigators are still working to identify the person or persons behind the clown accounts related to Friday's threats, which is a criminal investigation.
He said the Hampton Police Division is working with the FBI and Newport News Police Department in both investigations. He added the people using the account could face charges of threatening to kill by electronic means.
