An investigation is underway after multiple hoax calls disrupted the school day in over 28 districts in Massachusetts. The Massachusetts State Police confirmed that unfounded active shooter threats were made to schools, including Attleboro, Foxboro, Mansfield, and Taunton on Tuesday. Several schools initiated shelter-in-place or lockdown protocols, but they were lifted once the buildings were found to be secure. The calls are believed to be “swatting” calls that occurred a day after an actual school shooting in Nashville, leaving six people dead, including three children. Rhode Island State Police have also initiated an investigation after 14 districts in Rhode Island received fake calls on Monday morning, which officials believe were made by the same person. The Massachusetts State Police Fusion Center is currently working to identify the responsible party behind the hoax calls, and anyone found guilty could face felony charges.
