Another threatening message on a bathroom wall was found at Warren East High School last night.
Superintendent Tim Murley says it's important to treat each threat like it's the first one.
This is the second bathroom wall message at Warren East recently.
Murley says there are several leads, and he hopes to get the person doing this prosecuted as quickly as possible.
He did request extra security at the school as a precaution.
"We have some deputies in and out and around. You treat everything seriously and I'll always do that. You want to keep everybody safe. And that's what we will do. We'll do our best to keep everyone safe," Murley says.
Murley says attendance was not down compared to previous days this week.
He says students went about their day as usual.
