Brownsburg, IN (WTHR/CNN) - A cryptic threat posted on a school website in Indiana caused about 500 students to stay home on Thursday.
The FBI is investigating the threat made by hackers on the Brownsburg Community School website.
Investigators believe the message is in response to the anti-islamic video that has sparked violence around the world.
The message was taken down after less than an hour, but not before causing panic in the community.
"Some kids just didn't have a lot to say. Some were like, 'oh we're going to die, we're going to die, we're going to die,'" said Dee Frye, a bus driver.
School authorities said the threat is not credible and no sensitive information was accessed.
They do believe the website was chosen at random because it was easily hacked into.
Classes are scheduled to be held as usual on Friday.
