It was the end of the first day of school - and Brandon's Ecole New Era School on Louise Avenue was already on lockdown.
Police were called to a nearby house on 6th Street - and out of precaution - notified the school, which decided to keep students inside.
It all happened at the end of the day Wednesday - at around 3:20 pm - and the lockdown was brief, ending just past 3:30 pm.
Brandon Police say it turned out to be a false alarm, and no arrests were made.
Q Country News has called the Brandon School Division for comment.
