Police said an elderly woman entered the Canadian Western Bank (OTCBB:CBWBF), put down the packages, told a bystander that police would know what to do with it, and then left, the Canadian Broadcasting Corp. reported Thursday.

Officers ordered a dozen people to leave the building and sealed off a block along the street.

The bomb squad blasted the packages with a water cannon only to find a collection of memorabilia, including four war medals inside a tin box.

Inspector Dan Jones said police want to speak with the woman, whose identity isn't known. He stressed the incident isn't considered to be a criminal matter.
