Update 5.50pm: A television appeal is being screened in Vienna - to try and help trace a young Meath man, missing since yesterday.
Ross Hanlon (21) from Athboy was last seen around 2am on Friday morning.
He had travelled to the Austrian capital on a trip with some college friends, but became separated from the group during a night out.

"The police stations in Vienna are now doing a search.
"They are hoping that our reports tonight on our television station will help to find any clues about what is going on here in Vienna with this missing person."
