Two of the top detective posts in Dublin will be filled next week -- by two of the country's most experienced plainclothes men.
Det Supts Gabriel O'Gara and Walter O'Sullivan will take up new postings next Tuesday at Pearse Street and Blanchardstown Garda stations respectively, where they will be responsible for some of the toughest districts in the country.
Both officers have extensive experience in battling serious crime in different areas of Dublin over the past decade.
Roscommon native O'Gara, who is currently posted to Ennistymon, Co Clare, has served at Kevin Street and Ballyfermot Garda stations in the past.
He worked on a number of major investigations in the past, and helped secure a conviction against former IRA killer Bernard Dempsey for the murder of kickboxer James Curran in the Green Lizard pub on Francis Street four years ago.
Det Supt O'Gara also investigated the notorious criminal Mark Desmond, who was charged with murdering two young men and dumping their bodies in the Grand Canal in 2000. He also caught serial rapist Salmon Aslam Dar, who commuted to Dublin by train from Co Mayo and attacked women on the city's northside and Dublin 8.
Kerryman O'Sullivan is currently based in Kilkenny, but has served in Lucan, Clondalkin and Coolock in the past.
He worked on the high profile 'body in the suitcase' investigation in 2001, which led to the conviction of a man over the killing of Romanian Adrian Bestea, whose body was taken across Dublin in a bus before being dumped in the Royal Canal.
Det Supt O'Sullivan also worked on the Baiba Saulite killing case and the investigation into the killing of innocent Donna Cleary, a young woman shot dead at a house party in Coolock three years ago.
A senior source told the Herald: "These two positions are among the most important in the city in terms of battling gang crime. The detective chief at Pearse Street oversees the entire south inner city, and areas like Inchicore and Bluebell, while the officer on the west side oversees Blanchardstown, Finglas and Cabra.
"These are not positions for paperwork gardai, only the top frontline cops were considered."
Their transfers are among a number of new postings due to come into effect in the city in the coming week.
A significant appointment yet to be announced is that of a replacement for outgoing Det Supt Denis Donegan, who is soon to retire from his post at Crumlin.
Det Insp Liam Kelly is also being transferred to Crumlin station in the coming weeks, to oversee the policing of serious crime there.
