The recreation activities along Bremner Blvd — CN Tower, Ripley’s Aquarium and Rogers Centre — appear to have been the target of a threat which police have so far refused to make public. In addressing increased police presence in the heavily-barriered area, police have said there is a threat but refused to discuss what it is. This has caused annoyance among some who feel the public has a right to know the nature of such things. The likely reason for police caution is the fear of inspiring additional misfits to perhaps actually execute a threat. The use of a truck to hit crowds of people comes to mind.
