An Garda Síochána are to carry out a search in south Dublin as part of their investigation into the disappearance of Trevor Deely, who went missing 17 years ago.

Trevor, the 22-year-old son of Michael Deely, a senior official in Bord Bia at the time, worked for Bank of Ireland’s IT department when he disappeared.

He was last seen when he called in to Bank of Ireland on his way home from a Christmas party in December 2000.

CCTV footage showed him at Baggot Street Bridge on his route home. The Deely family has spent 17 years trying to find out what happened.

Garda investigating the case announced on Saturday that a search had begun at a woodland site in Chapelizod, south Dublin, in connection with the investigation into Trevor's disappearance.
