Canadian police have foiled a deadly plot that would have seen at least two people storm a mall and kill as many victims as possible on Valentine's Day before committing suicide, officials have said. A 23-year-old US woman, from Geneva, Illinois, a 20-year-old man, from Halifax, and a 17-year-old boy, from Cole Harbour, were reportedly arrested  on Friday morning following a tip-off to police. Another man, a 19-year-old Canadian, shot himself at his parents' home in Timberlea earlier that day after officers surrounded the property, police said. The suspects are yet to be identified. In a statement, Nova Scotia Royal Canadian Mounted Police Commanding Officer Brian Brennan said the deceased man and woman had intended to carry out the murderous plot at a Halifax mall.
