Another high school has received a threat.

Cardinal Spellman High School says a threatening email was received on Monday after school had already begun for the day.

Officials say they determined it was in the best interests of students to implement a "stay in place" protocol, which means that classes continue as scheduled with the building tightly secured.

After consulting with Brockton Police and their Risk Management Team it was determined that the threat was not a credible one.

However, a police presence is remaining on campus throughout the day particularly at dismissal time and all afterschool activities have been cancelled.

School officials say, as of now, classes will be in session tomorrow and for the remainder of the week.

The threat follows threats to Brockton High School and Whitman-Hanson Regional High Schools that lead to those two schools being closed on Monday.
