So me and my father went to Surrey Central City Mall to look around and eat and then go to Walmart. We first went to Best Buy and then I played on the Nintendo Switch there. And then all of a sudden a man told us to evacuate the building immediately, and then the alarm went off. I thought it was just the store, but no, it was actually the whole mall. Leaving everyone including us to leave the building. We weren't expecting this to happen. Mall security said there was an unknown security issue... Me and my father thought there was a fire at the building, or a mass shooting. Around 5:45 PM, 15 minutes before the Mall's closure on Sundays, people were being allowed to re-enter back in the building. But me and my father didn't go back, we just thought it was closed early.

so what happened?
