Police are investigating an anonymous threat to Durfee High School in Fall River that caused hundreds of students to stay home from school Friday. The Herald News reported that a student noticed a post on the social media app “SnapChat” warning students to stay home and threatening a “Florida pt 2” at the school, an apparent reference to last week’s school shooting in Parkland, Florida.

A junior at Durfee sent a screenshot of the original post- and a second threat – to the school principal, superintendent and other school officials.

In a press release Friday, Fall River Police confirmed they received a “several reports” about a threat to the school circulating on “SnapChat” on Thursday evening and they had increased security measures at the school in response.

“The Fall River Police Department takes any threat to our community and especially the safety of our students with the utmost concern. Due to the threat, increased security measures were taken by the Fall River Police to ensure the safety of our students at B.M.C. Durfee High School as well as all other campuses within our school district.

The Fall River Special operations Division, Fall River Police School Resource Unit and Fall River Public Schools Security Team implemented elevated security protocols and increased police presence both uniformed and undercover to ensure the safety of our students.”
