From Canoe.ca:
Police were probing a possible security threat at the Scotiabank Convention Centre in Niagara Falls Friday evening.
A call of a man with a weapon and a bomb at the convention centre was made to U.S. police around 6:30 p.m. Friday. The U.S. authorities alerted Niagara Regional Police to the call.
Police are searching the building and reviewing video surveillance to determine if there is truth to the call.
This was last Friday. Nothing was found.
