GREENFIELD — A 12-year-old boy is locked in a juvenile detention center after school officials found a handwritten note threatening a school shooting.

Administrators at Greenfield Intermediate School, 204 W. Park Ave., notified school resource officers after a piece of paper with the threat written on it was found, according to police.

“I am shooting up the school today. This is not a joke. Try and find me. I have a gun in my locker,” the note stated, police said.

School resource officers and administrators identified the boy — whose name is being withheld because of his age — as the student responsible for the note. He was arrested at school and taken to the Delaware County Juvenile Center in Muncie, a news release states. He’s being held there on a preliminary charge of intimidation, officials said.

The charge has been passed to the Hancock County Probation Office for review.

The school was able to identify the student involved quickly, so locking down was not necessary, police said.

No weapons were found, and no other suspects appear to be involved in the incident, police said.

The threat comes about a month after a school shooting in Parkland, Florida, that left 17 dead. Since then, dozens of threats have been reported at schools across the state.

A week ago, New Palestine High School officials investigated a threat made by a student there and deemed it not credible.
