METHUEN, Mass. (WHDH) -- Police said a Methuen teenager was arrested after he allegedly threatened to carry out Columbine-style attack on his high school.

Jacob Butze-Maille, 17, appeared in Lawrence District Court Friday. He was arrested Thursday and charged with threatening to commit murder and intimidation of a witness.

Prosecutors say he told a classmate that he was going to buy an AK-47 assault rifle and that he hated everyone at the high school and was going to shoot them. He is accused of telling the classmate he would shoot her first if she told anyone.

“It does not appear to us to be an unsupported threat, not to say it would’ve come to fruition and occurred,” said Chief Joseph Solomon of the Methuen Police Department.

Police aren’t sure if there was a specific plan, but said there was enough to raise eyebrows.

“At no time was anybody in danger during the school day,” said Solomon. “We have not found any weapons, but we have found some note material.”

The police department and superintendent credit an alert teenager for turning to the principal over the alleged threats.

“The girl deserves a well thank you,” said Solomon.

“We do not tolerate threats. Period,” Judy Scannell, Methuen Schools Superintendent.

The teenager will remain behind bars pending a dangerousness hearing set for Jan. 4.
