Polaris Montessori Elementary School was evacuated to École College Heights Elementary School on Friday.
The move was made at midday after police received information regarding threats directed at Polaris, both Prince George RCMP and the School District 57 said.
Parents were being contacted by school staff to make arrangements for student pick up at CHES while police were working to determine the exact source of the threat.
"As this is a stressful situation for all involved, police wish to remind everyone to be mindful of your driving and obey all the rules of the road, especially in and around the school zones," RCMP said.
In a social media posting, Polaris principal Tim Yule said that while police are investigating the threat, no incident occurred at the school and the evacuation was carried out as a precaution.
And in a statement issued late Friday afternoon, school district superintendent Marilyn Marquis-Forster said school "will be ready to welcome staff and students back to normal operations on Monday."
