There's no evidence an "unspecified internet threat" against Kentucky and Arkansas schools is credible, the FBI's office in Louisville wrote in a Monday tweet.

"FBI Louisville is aware of an unspecified internet threat against schools in Kentucky (08/28) and Arkansas (08/29). There is no evidence indicating this threat is credible. However, if you see something suspicious online or in person, contact local law enforcement or the FBI," the tweet said.

The threat spread on Facebook, with posts circulating the claim that a mass shooting would happen in an undisclosed location in one of the state's schools on Wednesday.

The Kentucky Office of Homeland Security's statement said the threats are at this time unsubstantiated but officials will monitor.

About 7:45 a.m. Tuesday, several schools in Anderson County were put on lockdown following reports of "two suspicious subjects on foot near Anderson County High School property," Anderson County Schools posted on its Facebook page.

Two 19-year-old men were reportedly arrested about 8:25 a.m. at a residence near the high school in Lawrenceburg, with police saying one of the teens had a BB gun.

Authorities said they do not believe the two men had any intention to cause harm. The teens were each charged with disorderly conduct and trespassing, LEX 18 reported.

In regards to the FBI's statement on an "unspecified internet threat" against a Kentucky school, Bullitt County Public Schools issued a statement Monday assuring parents and families that keeping children safe is "of the upmost importance to us."

"Bullitt County Public Schools has not been specifically named in any threat," the statement said. "we have security practices and protocols that are carried out on a daily basis to ensure that we do all we can to keep out students, staff and visitors safe."
