A Canadian court postponed making a decision on whether to grant bail to Karim Baratov, who was arrested in March on U.S. charges that he was involved in a massive hack of Yahoo email accounts, CBC reported Wednesday.

Baratov's lawyer requested that his client be released on bail, promising that he would remain at his parents' home in Hamilton, Ontario. The prosecutor argued the 22-year-old Kazakh-Canadian citizen was a flight risk and a threat to public safety.

Judge Alan Whitten said he would hold off on ruling until Tuesday, following a full-day hearing and private meeting with attorneys, according to a report on the website of Canadian public broadcaster CBC.

The United States has asked Canada to extradite Baratov to face charges that Russian intelligence agents paid him to break into email accounts, resulting in the 2014 theft of some 500 million Yahoo Inc YHOO.O accounts.
