The Cape Cod Times reports that the high schools in Bourne and Barnstable also received threats but students were not evacuated.

Quincy Police also responded to two additional high schools that received similar calls.
The investigation into the source of the threats is ongoing by several law enforcement agencies, including federal agencies, as similar threats were experienced in Maryland on Friday.
