Workers at a Tempe middle school checked students' backpacks as they arrived on campus Friday, after reports of a threat to the school.
According to a Facebook post from the Kyrene School District on Friday morning, a Snapchat post was discovered stating that "someone had heard about a threat to the Kyrene Middle School campus."
District officials reported the post to Tempe police, who say that while they do not believe the threat is credible, they are investigating the report.
The district says "out of an abundance of caution", there is an increased police presence at the campus on Friday, and staffers have been instructed to check backpacks as kids arrive at the school.
Tempe police confirm that multiple school resource officers, as well as patrol officers, have gone to the campus to provide extra security.
The Friday report is the third school threat reported in the Valley this week.
On Monday, police investigated a threat against Mountain Pointe High School posted on social media . The following day, a threat toward Maricopa High School was also reported .
