CALDWELL, Idaho (AP) — A judge has sentenced an Idaho man convicted of felony terrorism almost nine months after he was arrested for making fake bomb threats in Nampa.

Prosecutors say 22-year-old Grant Stevenson was sentenced Monday to 15 years in prison, with three years to be served before being eligible for parole.

Prosecutors say additional charges including the felony use of weapons of mass destruction were dismissed as part of a plea deal.

Authorities say Stevenson was arrested after the Nampa Police Department received social media messages in March warning them of multiple bombs placed in cars and an apartment complex.

Stevenson declined to address the court Monday.

Authorities say Stevenson had served three years in juvenile detention for bomb threats made at multiple schools in 2013.
