Portage Collegiate Institute was put on lockdown this week on Wednesday after RCMP in the city received a phone call from an unknown person making serious threats against the school.
An officer that was already in the school for an unrelated reason was told about the threats and asked the school to be placed on lockdown.
To ensure the safety of staff and students, numerous officers and a certified explosives detection dog were immediately sent to the school.
Officers and Police Dog Services completed a search of the area without any suspicious people or items being found.
The lockdown was lifted after the search.
Two people were detained and questioned during the investigation but were released because they weren’t involved.
The RCMP is focusing on identifying the caller as the investigation continues.
Anyone with information is asked to call 204-857-4445.
