Flagstaff schools were on high alert after learning about suspicious comments made on social media.
On Tuesday, the Flagstaff Police Department received reports about a tweet on Twitter in which the user wrote, "Pull a Columbine...shoot up my school then kill myself."
Officers reached out to multiple city schools to warn them about the threatening remarks, police said.
As a precaution, officers were patrolling near schools and were attempting to locate the person who wrote the messages.
On Wednesday, the author of the tweets, a juvenile, confessed to making the statements. He told police he didn't intend to follow through with the threats. Police searched the teen's home and did not find any weapons. A juvenile referral was completed, police said.
