A man in his 50s arrested yesterday on suspicion of murdering missing Kerry farmer Michael Gaine has been released without charge.
The man was questioned by detectives for the maximum period of 24 hours when he was released from custody at Killarney Garda Station tonight.
He was driven away from the station in an unmarked garda car.
Gardaí said that search operations, supported by local, regional, and national Garda units, other emergency services and the Defence Forces, are ongoing at Carrig East in Kenmare.
They added that Mr Gaine's family have been informed and are being supported by a garda Family Liaison Officer. The family have also requested privacy at this time.
Gardaí questioned the man about his relationship with the 56-year-old, who has been missing from his farmyard near Kenmare in Co Kerry for eight weeks.
It is also understood that the man was known to Mr Gaine.
From the outset of the investigation, gardaí from the Kerry division have had access to garda national support units and some - like the Garda Water Unit - have been deployed during the search for Mr Gaine.
The Garda National Bureau of Criminal Investigation operates under the Assistant Commissioner for Serious Crime. It regularly provides assistance to garda teams on the ground investigating serious crime.
Members of the Garda Dog Unit also participated in today's search with their dogs.
Throughout the weekend, attention was set firmly on Mr Gaine's farmyard, 8km from Kenmare.
The discovery of materials while slurry was being spread on Friday evening led to the area being designated a crime scene.
A huge examination and search of the farmyard and surrounding fields re-commenced, after the area was designated a crime scene.
The material found was confirmed to be human tissue, and more human tissue was recovered during the search.
There were sombre scenes as that was removed in a hearse yesterday evening for tests that are expected to confirm the material is the partial human remains of Mr Gaine.
Around 20 members of the Defence Forces joined gardaí on Mr Gaine's farm, with personnel combing fields searching grassland, vegetation and undergrowth where the slurry was spread.
An industrial unit for clearing drains also arrived at the farm.
The parish priest of Kenmare prayed for Mr Gaine in his farmyard yesterday afternoon.
Fr George Hayes said he prayed that the Lord would give strength to those who had been burdened by Mr Gaine's death.
"I offered prayers at the farm yesterday afternoon," Fr Hayes told RTÉ News.
"It seemed so incongruous to be praying for Michael in such circumstances on such a beautiful day."
"The parish of Kenmare keeps Mike Gaine and the Gaine family in our thoughts and prayers over these harrowing days."
Fr Hayes added: "When words fail us, all we can do is offer our presence and our prayer to God, that the Lord will strengthen and uphold all who are so heavily burdened at this time.
"We have a candle lighting in the sanctuary of our Church, Holy Cross in Kenmare, remembering Mike and holding in our prayer all who are so deeply affected by recent happenings."
Michael Gaine, also known as Mike, has been missing from his farm in Kenmare since 20 March.
Initially, his disappearance was treated by gardaí as a missing person's case.
That changed just over a fortnight ago when gardaí said they were satisfied Mr Gaine was dead and that they had re-classified his disappearance as a homicide investigation.
Gardaí renewed their appeal for information and said the investigation team can be contacted at Killarney Garda Station on 064 667 1160, the Garda Confidential Line at 1800 666 111, or speak with any member of An Garda Síochána.
