Schools in parts of northeastern Massachusetts and southern New Hampshire saw a visible bump in blue lights on Wednesday after a wave of automated robocalls claimed there were explosive devices on campus. Police and district leaders said K-9 teams swept the buildings and found no explosives, and classes stayed in session with an added security presence. Officials said they were taking the threats seriously while investigators worked to track down where the calls came from.
Tyngsborough Police Chief Shaun Woods said the town would step up patrols after at least three automated calls came into schools Wednesday morning and that investigators do not believe the messages are credible, according to Boston 25 News. Woods said the department later learned that similar calls were reported across the Northeast, including at multiple schools in Nashua. School officials said buildings would follow their normal schedules, with additional officers on site.
Which Schools Were Targeted And What Officials Found
Nashua Superintendent Mario Andrade told families that Bicentennial and Main Dunstable elementary schools received robocall bomb threats around 9 p.m. Tuesday, while Nashua North and Nashua South high schools and several other elementary schools received similar calls Wednesday morning. Law enforcement conducted K-9 sweeps and found no credible threat, according to Boston 25 News. Andrade wrote that “all students and staff are safe, and there is no active threat.” Police departments in Pelham, Litchfield and Hudson likewise said that threats in their communities appeared non-credible but that extra patrols and safety checks would continue.
Why Robocalls Keep Tripping Alarms
Robocall campaigns have surged nationwide this spring. YouMail’s robocall index found Americans received an estimated 4.2 billion robocalls in March 2026, reversing a brief dip and underscoring how easily hoax messages can spread, according to YouMail. New Hampshire authorities have also pursued enforcement aimed at voice-over-IP providers as part of a broader crackdown on illegal automated calls, per reporting by WCAX.
What Parents Should Expect
Districts said schools would continue normal operations while uniformed officers remained visible and school resource officers supported buildings. Officials urged families not to circulate unverified information and to contact local police directly with any details that might help the investigation.
Investigations into the robocalls are ongoing, and authorities asked anyone with tips to reach out to their local police department. This story will be updated as officials release additional information.
