The Irish Republic fell quiet at noon yesterday in honour of Garda Colm Horkan as his funeral began in his native Charlestown in Co Mayo.
One minute of silence was observed at Garda stations and in homes as the funeral at Saint James' Church was held amid Covid-19 restrictions that meant many who wanted to go could not.
Garda Horkan served four years of his career at Finglas Garda Station in north Dublin in the same unit as two other members who died on duty, Garreth Harmon (28) and student Garda Conor Griffin (25).
They were killed when the unmarked car they were in crashed while responding to a request for assistance from a patrol car pursuing a vehicle on May 15, 2000.
Inspector Andy Tuite led the parade in honour of Mr Horkan yesterday, and called the minute of silence on the road outside the station as gardai flanked it on both sides.
Members of Dublin Fire Brigade and members of the public also attended to pay their respects and support the Finglas gardai.
The tricolour hung at half-mast during the short and dignified ceremony. One retired Garda who knew Colm Horkan and served with him in Finglas said he was "a solid man from a young age".
"I've read all about him this last few days and it's obvious he didn't change as he got older. The things that are being said about him now could have been said back then too," he said.
"He was rock solid, a gentleman and an excellent Garda," he added.
The deaths of gardai Adrian Donohoe and Tony Golden were recalled to those who gathered outside Dundalk Garda Station to pay their respects to Mr Horkan yesterday.
Garda Chief Superintendent Christy Mangan said gardai in Louth, and specifically in Dundalk, "know the pain and feelings of loss that our colleagues in Roscommon and Mayo are experiencing today".
"The funeral of Detective Garda Colm Horkan brings back those most vivid memories from 2015 and 2013 when we tried to comprehend the sudden and senseless loss of Tony and Adrian," he added.
"Unfortunately we are all too familiar of the dangers that we as members of An Garda Siochana face every time we take up duty in order to protect and serve," said Mr Mangan.
