Belmont High School was closed Wednesday as police and fire officials investigated a bomb threat.
Belmont police wrote on Twitter that the district decided to close school for the day "out of an abundance of caution." Belmont Police Chief James MacIsaac said police were called about the threat around 6:30 a.m. Wednesday.
"At that time, the fire alarm was pulled and the school was evacuated," MacIsaac said.
There were no students in the building at the time, MacIsaac said, but there were an unspecified number of staff members. The chief was in contact with the superintendent of Belmont Public Schools as the investigation continued.
There was no immediate threat to the public, MacIsaac said.
On Thursday, U.S. Marshals arrested a New Hampshire man in connection with the threat at a Holiday Inn in Peabody, Massachusetts, Belmont police said. They did not name the 39-year-old from Ossipee.
Belmont detectives had obtained an arrest warrant for the man, suspecting him of making a false bomb threat. Other charges may be filed, including ones in federal court, police said.
