New CCTV footage shows a man "acting suspiciously" and talking to Trevor just before he was last seen
A reward of €100,000 has been offered for anyone with information on Trevor Deely who has been missing for over 16 years.
Gardaí and Trevor’s family held a press conference this afternoon to announce new information in the case.
The award money has been put up by an anonymous donor.
Enhanced CCTV footage from the night Trevor went missing shows a man acting suspiciously outside his Bank of Ireland workplace.
Gardaí are anxious to speak to the man and are calling for anyone with any information to come forward.
Speaking to reporters following the press conference, Trevor’s brother Mark said the family are “absolutely convinced that somebody knows something.”
“To date we have never been able to find that person or find that something,” he said. “Maybe technology has moved on and we can certainly see things clearer ourselves as a family through that footage.”
“We would be very keen that this individual would come forward – but not just him, maybe other people as well.”
He said that after 16 and a half years the help of the general public remains “crucial” to the investigation.
Trevor’s sister Michelle said that he would “never give up” on his family if the roles were reversed - adding “that is what keeps us going.”
His sister Pamela said: “Somebody must have been hiding some information over the last 16 years; somebody has to.”
“Somebody can’t just disappear into thin air,” she said.
Trevor Deely 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.
The footage released today shows the then 22-year-old calling in to his office at Bank of Ireland Asset Management off Leeson Street on his way home.
Gardaí said he had dropped in to the office to pick up an umbrella and had stopped inside to have a cup of coffee with a colleague.
The footage shows another man dressed in black acting "suspiciously" outside of the rear entrance of the offices before Trevor arrived.
The man appears to wait outside the building for over half an hour before his arrival.
At 3.34am – moments before Trevor approached the offices – the man stepped out onto the footpath and followed Trevor to the back gate of the building before starting to talk to him.
Trevor was last captured on CCTV passing the Bank of Ireland ATM on Haddington Road at 4:14 that morning.
Gardaí believe that the man who spoke to Trevor outside his workplace is the same man who is seen in the video passing the Haddington Road ATM just 34 seconds after Trevor.
Detective Inspector Paul Costello told Newstalk that the man, "waited 34 minutes there and he chose to move when Trevor passed."
"In our belief that is something we need to find out about; we need to know why he was waiting."
Trevor is described as being 6’1” in height and of slim build. He has short red/brown hair and fair complexion.
When last seen he was wearing a mustard and brown checked shirt, beige/grey corduroy flared trousers, dark deck shoes with white stripes and a green padded jacket.
He was carrying a large dark blue umbrella with white ACC Bank lettering.
Gardaí have been carrying out a complete review of the case since September of last year, culminating in this latest appeal.
“Our first appeal is for this male if he recognises himself to come forward and secondly for anyone else to come forward who may recognise him to notify us through Crimestoppers on 1800 25 00 25,” said Detective inspector Costello.
