A 57-year-old-man man remains in a serious condition in St Vincent's Hospital after being found unconscious on a pavement outside a Dublin city centre pub on Sunday morning.
The man was discovered outside Searson's Public House in Baggot Street between 2.30 a.m. and 3.00 a.m. on Sunday morning.
Gardaí are trying to establish what happened to him and believe there must be witnesses as there was a large number of people in the area at the time.
They are appealing for anyone who may have seen the man prior to the arrival of the ambulance to contact them in Donnybrook Garda Station at 01-6669200.
