The robbers made off with several pieces of jewelry and police are still on the hunt.\nIn a release, Calgary Police said they got called to Sunridge Mall around 1:30 p.m. on Saturday afternoon, August 1. Two masked men had entered Paris Jewelers where they "deployed tear gas and displayed a significant amount of violence."\nEditor's Choice: YVR Had Three Air Canada Flights With COVID-19 Cases On Board Last Week\nInside the store, police say they used pepper spray and threatened staff with firearms. They then fled the scene in a "brown/gold SUV" with stolen jewelry.\nMeanwhile, their pepper spray managed to seep into the mall's ventilation system, spreading chemicals throughout the building, reported CBC News. One shopper had to be taken to the hospital in non-life-threatening condition.\nEven the fire department was called, who at first thought there was a fire due to the thick haze in the air, according to CTV News. When they realized it was actually a chemical substance, the entire mall had to be evacuated.\nTwenty patients were assessed by EMS at the scene. Other than the one hospitalization, no one else was hurt.\nCan you help identify two men who committed an armed robbery at Sunridge Mall in #yyc earlier today?

EMS and firefighters had chipped in to help the decontamination process, but it could be hours until all the tear gas is cleared up, reported CTV News.\nA witness at the scene alleged that the robbers didn't just use tear gas — they deployed smoke bombs too. Daniel Hurstfield told CBC he was walking when a "canister hit the ground about 10 metres in front of him." Black smoke began to billow out from it.\n"I was wearing a mask in the mall anyway, but it didn't affect my eyes, it didn't affect my breathing, it was just a very charcoal-y smell," he told the outlet.\nPolice are still hunting for the suspects and they need your help.
