Authorities have determined a possible threat made online Tuesday involving Ironwood Ridge High School was false.

The Oro Valley Police Department received information from citizens who saw a post on the website that showed an image of the school with text that said, “The whole world would know the high school next week, or something to that effect,” said Lt. Kara Riley, police spokeswoman.

Police contacted the FBI, and the joint investigation revealed that the person who posted it is a minor who was referring to an upcoming sporting event at the school, Riley said.

“There was no malicious intent at all. It was just to support this school.”

No charges will be filed because no laws were violated, she said.

The Amphitheater Public Schools district said in a news release that it will have an increased police presence at the high school for a few days as a “cautionary measure.”
