TORONTO - An executive of Chinese tech giant Huawei is suing the Canadian government, its border agency and the national police force, saying they detained, searched and interrogated her before telling her she was under arrest.

Lawyers for Meng Wangzhou said Sunday they filed a notice of civil claim in the British Columbia Supreme Court. Canada arrested the daughter of Huawei's founder at the request of the U.S. on Dec. 1 at Vancouver's airport. Meng is wanted on fraud charges that she misled banks about the company's business dealings in Iran.

The suit says that instead of immediately arresting her, authorities interrogated Meng "under the guise of a routine customs" examination and used the opportunity to "compel her to provide evidence and information."

Meng is awaiting extradition proceedings.
