The Garda Síochána Ombudsman Commission has refused to confirm reports that it has begun an investigation into the circumstances of a traffic accident in December 2014 involving the Metropolitan Mayor of Limerick Fianna Fáil Councillor Jerry O'Dea.

Mr O'Dea was involved in an accident in which his car overturned and he was treated in hospital. Nobody else was involved in the accident.

He subsequently issued a statement confirming he had been involved in a traffic accident and that he cooperated with gardaí. He was informed in May 2015 that no further action was to taken against him.

Gardaí began an internal inquiry into the matter when it became public, amid allegations that Mr O’Dea had been found to be over the legal limit for alcohol levels at the time of the accident.

It is now understood that GSOC are following up on a complaint made to them about the matter and are investigating if the garda inquiry was properly conducted, was without influence from gardaí or someone outside the force and why no prosecution followed.

A spokesperson for GSOC has said they do not give out information on complaints they receive from the public.

Anti-Austerity Alliance Councillor in Limerick city Cian Prendiville, who said he did not make the complaint, welcomed the news that the matter is to be investigated by GSOC.

He said conclusions of the internal garda inquiry into the issue should also be made public.

Mr Prendiville said they have sought support from fellow Limerick city councillors on a number of occasions for a public inquiry into the matter in the public interest. He added they also called on Mayor O'Dea to publicly refute the allegations but he has refused.

Unless the inquires into this matter are made public it reeks of cronyism and corruption, he said.
