Penalty points complain considered
One of the whistleblowers behind the penalty points controversy is considering asking the Garda ombudsman to launch an independent investigation into his allegations.
John Wilson, who retired from the force just weeks ago, said he has only become aware in recent days that he could make an official complaint to the force's official watchdog.
The Garda Ombudsman can not probe allegations by serving officers - as they are considered internal matters - but has confirmed it would have to consider any complaint from someone who has stood down.
Relations between the force and the Ombudsman have already plunged to an all-time low after its inquiry into alleged Garda collusion with drug trafficker and alleged informant Kieran Boylan.
Mr Wilson has branded a whitewash the internal Garda investigation into allegations by him and another anonymous whistleblower of widespread wrongdoing over wiping of fixed penalty notices for motoring offences.
He told the Press Association: "I very, very strongly am considering making a complaint to the Ombudsman. I'm seeking legal advice in relation to the matter."
He added: "We are both standing over the allegations that we have made."
Garda Commissioner Martin Callinan has accepted it is still possible for the force's watchdog to launch its own investigation. It has also emerged prosecutors are examining fraud allegations against a serving Garda officer at the centre of a separate internal inquiry into improper quashing of fixed penalties.
Mr Wilson said he went directly to management over his concerns about a superintendent. Mr Callinan has confirmed that a probe was launched into this case, and a file has been sent to the Director of Public Prosecutions (DPP). It is understood the unnamed officer is continuing to work on duty pending the outcome of the state prosecutor's decision on the findings.
Under cross-examination by a powerful parliamentary watchdog on Thursday, Mr Callinan said no files were sent to the DPP over the wider investigation into the wiping of penalty points by officers because there was no suspected criminality.
