The search in Chapelizod lasted for more than a month
A search in west Dublin connected to the disappearance of Trevor Deely has finished, with gardaí saying no evidence was found.
The search was being carried out at a site in Chapelizod.
In a statement, gardai thanked the public for their patience during the search operation.
They said: "Unfortunately nothing that furthers the search for Trevor was located during the search. The site remains closed to the public."
It comes despite a gun reportedly having been uncovered at the site shortly after the search began.
Gardaí have now renewed their appeal for anyone who may have information on Trevor’s disappearance to contact the incident room at Pearse Street Garda Station on 01-666-9000 or the Garda Confidential Line on 1800-666-111.
Excavation work at the site in Dublin got underway last month, after gardaí received new information relating to the Kildare man.
Mr Deely has been missing for nearly 17 years.
The then 22-year-old went missing after attending his work Christmas party on Friday December 8th 2000.
He was last seen on CCTV footage crossing Baggot Street Bridge and heading towards Haddington Road in Dublin city centre.
Gardaí launched a complete review of the investigation last year.
In April, a fresh appeal into his disappearance was issued after enhanced CCTV footage showed him talking to a man who detectives believe was 'acting suspiciously'.
