Vancouver, Canada (CNN Business) The United States is claiming that the chief financial officer of Chinese tech giant Huawei covered up violations of sanctions on Iran, according to Canadian prosecutors.

Meng Wanzhou, who was arrested in Vancouver and faces extradition to the United States, is believed to have helped Huawei circumvent US sanctions by telling financial institutions that a Huawei subsidiary was a separate company, prosecutors said at a hearing Friday to determine whether Meng should be released on bail.

Her lawyer said that she has ties to Canada and is not a flight risk. The judge, after hearing arguments from Meng's lawyer and prosecutors, did not rule on bail. The hearing will resume Monday at 1 p.m. ET.

Previously, details surrounding why Meng, 46, had been detained were limited due to a press ban. A judge had accepted Meng's request to bar both police and prosecutors from releasing information about the case prior to the hearing. The ban was lifted on Friday.

A judge in the US District Court for the Eastern District of New York issued a warrant for Meng's arrest on August 22, it was revealed at the hearing Friday. She was arrested on December 1.
