Four people were taken to hospital for irritation to the eyes and throat after somebody pepper sprayed the Ilot Voyageur bus terminal near the Berri-UQAM metro station.

Police and firefighters rushed to the building just before 11 a.m. Friday after occupants complained of a foul smell and irritation.

Police representative Francois Collard later said that video surveillance tapes would be studied in attempt to determine who sprayed the noxious mist.

Berri between De Maisonneuve and Ontario was closed to traffic for some time during the crisis.
