Cumberland County sheriff’s deputies arrested an 11-year-old boy Wednesday on a juvenile charge of terrorizing, after a bomb threat was found in the library at Gray-New Gloucester Middle School.

The school’s staff was alerted to a threat found on a combination scanner-printer in the library that said a bomb was in the school, according to a press release from the sheriff’s office.

The school was evacuated and bomb-sniffing dogs from the Maine State Police and Portland Police Department were brought in to search for a device. None was found.

School officials worked with detectives and determined that the threat had come from a computer assigned to a particular student. The 11-year-old boy was identified, issued a juvenile court summons charging him with terrorizing – felony because a public building was evacuated – and released to the custody of his parents.

The case was turned over to the Cumberland County District Attorney’s Office for prosecution.
