An unknown substance sent to the office of Quebec Premier Jean Charest in Sherbooke and nearly a dozen other locations appears to be benign.

Montreal police said a total of nine packages were reported at MNAs' offices, the French-language television station TVA and Loto-Québec on Wednesday morning.

Firefighters were called in to assist at several locations where the packages were delivered.

At least two packages were discovered in Sherbrooke and another in Quebec City.

One of the packages has been tested and contained a white substance found to be baking soda, police said.

All were signed by a group called Forces armées révolutionnaires du Québec.

No injuries were reported.

Police are still investigating.
