A Calgary woman contends someone sprayed bear or pepper spray on Occupy Calgary’s library and information tent. Though Occupy members were cleaning the area and warning people off when Mary March arrived with her three children yesterday, some of the noxious  substance affected her 11-year-old son and 5-year-old daughter.

"One of my children walked into the tent and we all yelled at him, ‘get out! get out!’ but he still had got residual spray on his mouth. And my daughter who just walked by the tent got it on her face as well," says March.

March and her family were at Olympic Plaza for a day of skating when they dropped by the Occupy camp for its "meet and greet."

While most Occupy Calgary protestors are at court today to fight a city eviction order, Steven Loo remained at the campsite. Loo says that as he understands it, someone sprayed the area around 5:00 a.m.; he could smell it when he arrived that afternoon.

Loo says the protestors organized their own security patrol in groups of two or three after members of the public tried to remove tents.

March called police and 3-1-1 but has so far received no conclusive response. She says her children are fine, but would like the city to view footage recorded on CCTV cameras installed in the area to investigate the spraying.

A Calgary Police spokesman says he is aware of the incident but no official report has been made to police.
