A graduation ceremony at a local school was disrupted Thursday evening while police investigated a threat.
Parents and students had to leave the building after a bomb threat during the eighth grade graduation program at Morristown Junior and Senior High School.
Shelby County sheriff's deputies called in Indianapolis Metro Police explosives experts to assist in a search of the building.
Students and parents were allowed back inside the school once police gave the all clear.
An investigation into the origin of the threat is underway.
