ANTHEM, Ariz. -- The Maricopa County Sheriff's Office is investigating a threat that targeted an Anthem school and Circle K store.
A Circle K clerk called the sheriff's office about 2 a.m. Friday saying a threat was called into his store on Daisy Mountain Drive near Interstate 17.
The caller reportedly told the clerk he had placed a package at a gas pump and said, "Remember Columbine, that will happen at the school near your store."
The sheriff's office said deputies found no substantiated threat at local schools or the Circle K, but additional deputies were placed in the area and surrounding schools were notified.
They are still investigating where the threat originated.
A spokeswoman with the Deer Valley Unified School District said Boulder Creek High School, the school nearest to the Circle K, was notified of the threat by deputies Friday morning but told to proceed with classes as normal.
After a Facebook message was posted about the threat and Anthem Preparatory Academy went on lockdown, Deer Valley Unified School District emailed information confirmed by the sheriff's office to all parents in the district as phone lines were down, the spokeswoman said.
