Wareham Police have charged two elementary school students with making false bomb threats in two separate incidents.

Minot Forest Elementary was evacuated on March 25 after the sentence "I want to blow up the school" was found written on a bathroom wall, according to a letter sent to families and staff from Principal Joan Seamans.

Police learned on April 14 of a bomb threat posted on a social-networking website targeting John W. Decas Elementary, according to a Police press release.

The Wareham Fire and Police departments determined that both threats were false and there was never any danger to students or teachers.

School Resource Officer Mary Walker and Police Detectives determined that two juvenile students, one from each school, were responsible for the pranks, according to the press release. Each student faces a Juvenile Clerk Magistrate's hearing in Wareham's 4th District Court at a later date.

There have been a number of bomb threats at Wareham schools in recent weeks.

Police arrested Wareham High School student Isaiah Lopes, 18, of Wareham, April 14 and charged him with making a false bomb threat. The school was evacuated April 13 after a note was found indicating that there was a bomb in the auditorium, according to a Police press release.

The maximum punishment for making a false bomb threat is 20 years in a State Prison and up to a $50,000 fine.

On April 6, Wareham Middle School was evacuated after a suspicious comment was found in a student bathroom, according to a letter sent to families and staff by Principal Howard Gilmore. That investigation is ongoing.

Superintendent Barry Rabinovitch said it's not unusual to receive one or more bomb threats per year at a particular school.

"Unfortunately there is a copycat mentality, and if you have one you may have another," Rabinovitch said. "Each perpetrator is being handled by giving the maximum consequences up to and including expulsion if the facts of the case warrant such a consequence."
