The Peterborough Victoria Northumberland and Clarington Catholic District School Board is clarifying details released by Cobourg Police Service following Monday’s incident at St. Mary Catholic Secondary School.
In an earlier media release, Cobourg Police stated they were actively investigating “a report of threats” at the school. As part of that investigation, officers conducted a search of the building and indicated the school had been placed in a “lockdown until further notice.”
However, Communications Manager Mark Guinta said that information was incorrect.
“The school was placed in a Hold and Secure, not a Lockdown as has been erroneously released,” said Guinta.
He explained that once police assessed the situation, the response evolved.
“Once police determined that an evacuation was the appropriate next step, the school immediately transitioned to that protocol. These decisions — including the timing and the move to our evacuation site, the Cobourg Community Centre — were made by law enforcement to ensure the most controlled and safe environment possible.”
Following the incident, school principal Jill Barker stated that both Cobourg Police and the Ontario Provincial Police conducted a “thorough sweep” of the building and ultimately cleared it.
When asked to clarify what that “thorough sweep” involved, Guinta directed further questions to Cobourg Police.
“Please refer those to the Cobourg Police Service, as they could answer how they conducted their investigation and how they cleared the school,” he said.
