Police want to hear from anyone who saw anything suspicious on Jolliffe Avenue on Dec. 6.
Specific details about the threats are not being provided and Const. Josh Cunningham said there is a reason for that.
“Those details will only be known to someone involved. So at this point, investigators are not elaborating,” he said.

Investigators with the OPP’s major crime and forensic identification units are examining the source of the threats.
Police said they believe it is an isolated incident.
