ADA, Okla. (KTEN) — Ada City Schools canceled all classes Friday due to a threatening message.

At approximately 1 am Friday, local law enforcement informed school officials of the threatening message that was directed at the district.

"We spent a considerable amount of time last night with police department officials discussing what we might do, and at the end of the day, it comes down to being as safe as you possibly can," Anderson said. "That's our highest priority: Keeping our kids, faculty, and staff safe. You can never go wrong by canceling school. But, unfortunately, you can go wrong by not, so we will always take the safe approach and air on the side of caution."

In a message sent to parents, faculty, and staff Friday morning, Superintendent Mike Anderson said even though the communication was not specific, the manner in which the threat was communicated and the language that was used led school officials and law enforcement to believe that the information received should be deemed credible.

"The way it was communicated and the language used led us to the thought that we needed to determine the credibility of what we read," Anderson said.

Public safety agencies, including Ada police and school district officials, are in constant contact, and a full investigation is underway.

"This is an ongoing investigation. It's still very preliminary, but hopefully, we will be able to gain some traction and find out a little bit more today," Anderson explained. 

Anderson said when situations like this occur, communication is essential.

"Like many other times, it happened in the middle of the night," Anderson explained. "I spent the night at the police station and this morning in my office just trying to communicate with everyone."

School officials will provide parents, faculty, and staff with additional information as it becomes available.
