A detective garda and a director of a car sales firm targeted by the Criminal Assets Bureau (CAB) are both to face trial on charges linked to a major investigation into alleged garda corruption.

The investigation into alleged garda wrongdoing and malpractice in the Southern Division is being led by the National Bureau of Criminal Investigation (NBCI), which is based in Dublin.

Detective Garda David Bourke, 48, with an address at Main Street Oola, Co Limerick, was charged with "corruptly obtaining a monetary gift, consideration or advantage from Stephen O'Sullivan", a director of Bawn Motors, a car sales firm located at Ballysimon Road in Limerick.

It is also alleged Detective Bourke obtained the monetary gift during the course of his employment as a garda for revealing to Mr O'Sullivan confidential information about a CAB investigation in relation to Bawn Motors.

Mr O'Sullivan, (37), with an address at Farrehy, Broadford, Co Limerick, was charged with one offence.

It is alleged that he corruptly gave or agreed to give Det Gda Bourke a monetary gift, consideration, or advantage, for Det Gda Bourke revealing to him confidential information concerning a CAB investigation into Bawn Motors, of which Mr O'Sullivan was a company director of at the time.

All three charges are alleged to have occurred on 22 December, 2018 at Bruree, Co Limerick.

Both accused were each granted bail, on their own bonds of €300, which does not have to be lodged.

Appearing before Limerick District Court both defendants, who appeared separately, only spoke to confirm their signatures on the bond sheets, which were signed in court.

Detective Inspector Michael McNulty, NBCI, told the court he arrested Det Gda Bourke at 8.25am this morning, at a location in Co Tipperary.

The court heard Det Gda Bourke was then taken to Shannon Garda Station, where he was charged with two offences.

He "made no reply" to each charge after caution, it was heard.

Solicitor Tom Kiely, representing Det Gda Bourke, said he had "no questions" regarding his client's arrest.

"Consent to bail with conditions attached have been agreed," Mr Kiely told the court.

Judge Marian O'Leary granted Det Gda Bourke bail on a number of conditions.

Detective Insp McNulty said the DPP had directed Det Gda Bourke face trial on indictment.

Detective Sergeant Dave Gilmore, NBCI, gave evidence of arresting Mr O'Sullivan this morning in Broadford, Co Limerick.

Mr O'Sullivan, who the court heard is currently working in Newmarket, was also taken to Shannon Garda Station, where he was charged with one offence.

Mr O'Sullivan granted bail on a number of strict conditions.

Judge O'Leary remanded both defendants on bail, to appear before Limerick District Court again on Friday, 13 September, for service of the book of evidence.
