A teen who admitted to being “mad at the school’’ when he used an attendance phone line to make a bomb threat against Lowell High School was sentenced to jail and probation on Tuesday.

Michael Tyler Buckley, 18, was convicted of making a false report or threat of a bomb stemming from the late August incident. It’s a felony punishable by up to four years in prison.

Kent County Circuit Court Judge Donald A. Johnston placed Buckley on probation for two years and sentenced him to six months in the Kent County Jail, with credit for 83 days already served. The judge approved possible early release to the Alternative Directions program.

Buckley contacted the Lowell High School attendance line and reported that there was going to be a bomb that would go off on Aug. 30, court records show. “Mr. Buckley made the call from his cell phone to the attendance line and did not block his number,’’ according to a probable cause affidavit.

A Kent County sheriff’s deputy had prior contact with Buckley and had his cell phone number, court records show.

“Mr. Buckley admitted to making the calls because he was mad at the school,’’ a detective wrote in court records. Buckley specifically targeted an assistant principal for disciplining him in the past, the detective wrote.
