A man who was questioned over the disappearance and death of Co Wexford woman Fiona Sinnott in 1998 has been released without charge.
However, detectives working on the case hope to be in a position to bring charges in the near future. The man who is in his thirties, was arrested in the Wexford area this morning and was questioned at the New Ross Garda Station, under Section 4 of the Criminal Justice Act for 12 hours.
He was one of six people arrested and questioned in connection with Ms Sinnott's death. It is understood that many of those questioned are friends or relatives.
A second man was also released without charge this evening. Two women remain in custody. One is being questioned in New Ross Garda Station and and the other is being held at Enniscorthy New Ross Garda Station Section. Both were arrested under Section 30 of the Offences Against the State Act.
Gardaí have received what they say is "very significant" fresh information on the disappearance of the woman, who is presumed dead.
They have already identified a chief suspect, and believe the new information may solve the case and lead them to Ms Sinnott's remains. Her case has been one of the most high profile missing persons inquiries in the last decade.
Gardaí yesterday renewed their appeal for information on the 19-year-old's disappearance.
The last person known to have seen Ms Sinnott alive was her ex-boyfriend, Mr Seán Carroll, the father of her daughter, Emma, who is now eight.
On Sunday, February 8th, she was drinking in Butler's pub in Broadway, near Rosslare.
Mr Carroll has told gardaí he spent the Sunday night at Ms Sinnott's rented cottage in the townland of Ballycushlane, where she lived alone. When he left the following morning, February 9th, she was still in the house. There has been no sighting of Ms Sinnott since.
In 1999 detectives involved in Operation Trace, the Garda investigation into the cases of six missing women, came to Wexford but failed to turn up any new leads. Afterwards, gardaí were said to be satisfied there was no link between Ms Sinnott's case and others.
Operation Trace was set up seven years ago by then Garda commissioner Pat Byrne to review the files of Ms Sinnott, Josephine Dullard, Deirdre Jacob, Ciara Breen, Fiona Pender and Annie McCarrick.
