MONTREAL -- Police say there’s a link between the seizure of explosives several hundred kilometres northeast of Quebec City and the evacuation of several homes in Montreal today. A school was also locked down as police carried out a search warrant in a nearby apartment building. Provincial police spokesman Claude Ross says three people were arrested and one ton of explosives was found in a van in Mont Joli, about 350 kilometres east of Quebec City. He says the vehicle was intercepted by police outside a doughnut shop, adding that the explosives were stolen from a local contractor.
