A 17-year-old boy was charged Monday in Family Court with making a false bomb threat to Scituate High School.
Police said the student made a threat on social media early Sunday to "blow up" the school. Another student told police and school officials.
An automated phone message about the threat and investigation was sent to parents.
Police said the school was searched and that no explosives were found.
The teenager, whose name was not released, surrendered to police Sunday night.
