GARDAI have expressed shock at the sudden passing of one of the Dublin's top young officers.
Sergeant Bryan McGlinn (33), from Store Street Garda Station, was found dead at his home on Sunday.
The officer was regarded as one of the most promising up and coming talents in the force and had worked on a number of major cases.
Garda Commissioner Martin Callinan paid tribute to Sgt McGlinn, a father of two young children, describing his death as "tragic" and a "very, very sad passing".
He told the Herald: "Brian was a very, very valued and trusted member of our garda community and I know that his colleagues are devastated as indeed we all are with the news this morning of his passing."
Sgt McGlinn had complained of headaches after striking his head while attending the Leinster rugby game at the Aviva Stadium last Saturday. He was discovered by his wife on Sunday evening after she returned from a trip to Cork.
He had two children, one aged three and the other just five months.
The Glanmire, Co Cork, native was one of the detectives who in 2005 captured thief Juan Carlos Guzman Betancourt -- known as the Colombian Pimpernell -- a fraudster wanted by police across the world.
He was a top detective in Harcourt Street at the time of the case, and was later promoted to sergeant at Store Street.
Former Detective Superintendent PJ Browne, who worked with Sgt McGlinn at Harcourt Square on the Guzman Betancourt case described him as a very skilled detective.
"One of the great traits I found in Brian as a young detective was his tenacity as an investigator," he said. "Once he got the scent of the criminal he would not let go until he was caught."
An autopsy will take place to discover the cause of Sgt McGlinn's death. It is thought he died from a medical condition.
