THE whistleblower who exposed alleged corruption in two Reserve Bank companies told five top bank officials of his explosive concerns, only to be forced out of his job and warned to keep quiet.

The revelations about what the former executive Brian Hood has told the federal police investigating the scandal raise serious questions about whether Reserve officials risked breaking laws by misleading Parliament, covering up corruption or victimising a whistleblower.

The revelations increase pressure on the Reserve governor, Glenn Stevens, and add to calls for a full inquiry into the scandal, which involves allegations that foreign agents paid bribes while working for Reserve subsidiaries.

The police have documents in which Mr Hood claims that in 2008, after he raised corruption concerns, he was told by an assistant Reserve governor, Bob Rankin, that his job ''had become untenable''.
