Residents of Halifax, Nova Scotia were on edge today after police announced they had foiled a mass shooting plot that was to take place Saturday in a “public venue,” which police determined was to have been the Halifax Shopping Centre.

NBC News reports:

A man found dead at a home in Halifax, a Canadian man and a female American suspect had been planning to go to a “public venue … with a goal of opening fire to kill citizens, and then themselves,” police said.

A 19-year-old male suspect shot himself to death after police were tipped off about the plot and surrounded his home in Timberlea at about 1:20 a.m. local time (12:20 a.m. ET) Friday.

Police say they don’t believe the plot was culturally linked and therefore an act of terrorism; rather, it was the plan of a “group of murderous misfits.”

Despite the news that all suspects were either dead or in custody, panic managed to strike the Halifax Shopping Centre Saturday night after someone reported an “active shooter” in the mall.

Halifax police determined that the “active shooter” was actually a group of children playing with a sling shot inside the mall.

Shoppers were not pleased.
