Police say a large quantity of unidentified white powder was found at the IKEA warehouse in Brossard Wednesday afternoon.

The substance was discovered at about 2 p.m. Employees were in contact with it, but none have reported any symptoms so far.

Police returned to the area Thursday morning and took samples. They believe the powder is likely baking soda.
