McLeod noted that a bail hearing has been set for this Friday, but declined to offer any further details on the case, citing a publication ban that he said was requested by Meng.

The report states that Meng is accused of violating the current USA trade embargo against Iran.
Huawei said it had little information about the charges and was "not aware of any wrongdoing by Ms Meng". "The ban was being sought by Ms. Meng".
Representatives of Huawei, one of the world's largest makers of telecommunications network equipment, could not immediately be reached for comment by Reuters. She was detained while transferring between flights, the firm said.
"The company believes the Canadian and US legal systems will ultimately reach a just conclusion".
US authorities are investigating whether Chinese tech giant Huawei violated sanctions on Iran. "Americans are grateful that our Canadian partners have arrested the Chief Financial Officer of a giant Chinese telecom company for breaking USA sanctions against Iran".
Several months after Donald Trump signed a bill into law preventing USA government agencies from buying certain products from the Chinese electronics manufacturer, Huawei's CFO has been arrested in Canada.
The US later replaced the ban with a fine and governance changes.
Trump has threatened to raise tariffs on Chinese goods in response to complaints that Beijing improperly pressures foreign companies to hand over technology.
The news comes the same day Britain's BT Group said it was removing Huawei's equipment from the core of its existing 3G and 4G mobile operations and would not use the Chinese company in central parts of the next network.
