VANCOUVER -- A hearing continues today in the extradition case of Huawei executive Meng Wanzhou, who was arrested at the Vancouver airport in 2018 at the request of American officials.

B.C. Supreme Court heard last week the border officer who led Meng's immigration exam before her arrest doesn't believe RCMP asked him to collect the passcodes to her phones.

Sowmith Katragadda told an evidence-gathering hearing he couldn't recall where the idea came from.

The court has heard the passcodes were collected as part of the border exam process and shared with the Mounties by mistake, along with Meng's electronic devices.

Meng is wanted in the United States on fraud charges based on allegations related to American sanctions against Iran that both she and Chinese tech giant Huawei deny.

Her lawyers are collecting information they hope will support their allegation that Canadian officers improperly gathered evidence under the guise of a routine border exam.
