A poster campaign is to begin in Irish prisons in a bid to track down Trevor Deely.

The bank worker was 22-years-old when he went missing after his Christmas party in Dublin 19 years ago.

He was last spotted on CCTV on the Haddington Road in the early hours of December 8th, 2000.

It's believed to be the first time an appeal is being made directly to inmates to solve a missing person case.

Numerous Appeals

Despite numerous appeals, a €100,000 reward, and a search of land in Chapelizod in 2017, his disappearance remains a mystery.

The posters will be displayed in areas where prisoners make phone calls along with visitor areas.
