East Hamilton middle and high school Principal Gail Chuy sent out a voice message to parents of students at the school this morning alerting them of a threat found at the school.
Chuy said a suspicious statement reading, "the school shall pay," was found on a bathroom wall.
"In light of recent similar incidents at other Hamilton County school we are investigating and all appropriate procedures are in place," Chuy said on the voice message.
She assured parents that law enforcement is investigating and safety is the school's top priority.
Hamilton County schools Assistant Superintendent told the Times Free Press that once a school receives a threat law enforcement is immediately notified.
"If the threat is found to be credible, action will be taken quickly to ensure the safety of all students and staff at the school," McDade wrote in an email.
He added that some threats may be copycat behavior, as two other schools in Hamilton County have received threats in the past two weeks. He said regardless, all threats are taken seriously.
On Tuesday, about 70 percent of Ooltewah High School students were absent after several threats of a shooting were also found on a bathroom wall.
Last week two students at Signal Mountain Middle High School were expelled for making threats to shoot people at the school.
