A judge declined to revoke bail yesterday for a former Connecticut hedge fund adviser awaiting sentencing for a major fraud scheme.

Prosecutors had said Francisco Illarramendi failed to disclose a tax refund despite an asset freeze. He pleaded guilty last year to fraud and conspiracy to obstruct justice in a scheme to conceal huge losses. Prosecutors say Illarramendi transferred money among investment accounts without telling clients, falsified documents to deceive investors and used money provided by new investors to pay out returns he promised to earlier investors.

Authorities said losses could run into the hundreds of millions. The pension fund for Venezuela’s state oil workers accounted for most of the investment in the hedge funds.
