East Hamilton School Principal Gail Chuy sent a message to parents of students at the school telling them that another threat was found today.
Chuy said another message was written on the bathroom wall.
"The message was directed at me personally, not at the school," Chuy said, adding that law enforcement is investigating the threat.
Hamilton County Juvenile Court Administrator Sam Mairs said making false threats is a Class C felony in Tennessee, and can be punished with three to five years in jail and a fine of $10,000.
"At the end of the day this is more than kids being kids," Mairs said. "[Making threats] is downright criminal."
In the message sent to parents Thursday, Chuy added that a "troubling picture" was also circulating among students today, and that law enforcement has determined that the picture was photoshopped and a hoax.
The source of the picture has been identified, and Chuy said they have been removed from school at this time.
Due to the recent threats, Chuy said she and law enforcement will be available tonight to talk to parents at the school at 5:30 p.m.
