A MAN on remand in Mountjoy Prison has been questioned by gardai about a Cork murder.
The death of Keith Flanagan (36) last October was originally treated by gardai as suspicious, but the case has now been upgraded to a murder investigation.
Mr Flanagan, from Luttrell Park, Carpenterstown, Dublin, was found lying semi-conscious on the street at Patrick's Quay in Cork on October 3 last.
A pedestrian raised the alarm when they spotted Mr Flanagan lying on the pavement with blood pouring from his nose.
He was rushed to Cork University Hospital (CUH) but his condition quickly deteriorated. Despite major surgical intervention, he died two days later from head injuries.
It was initially unclear whether the Dubliner had fallen and struck his head on the pavement or been attacked.
Gardai now believe Mr Flanagan was assaulted around 10pm on October 3 in the vicinity of Patrick's Bridge. He stumbled a distance up the quay before collapsing on to the street.
The Dublin man, who suffered from a pre-existing medical condition, had been staying in a hostel in Cork city centre for just two days before being attacked.
The father of two was living in Dublin but travelled to Cork to visit a friend while his parents went on a Spanish holiday.
On hearing the news of their son's injuries, they immediately flew back to Ireland and raced to his bedside.
A full post-mortem examination was later conducted by Assistant State Pathologist Dr Margaret Bolster at CUH.
Gardai refused to release its findings for operational reasons.
It is understood that CCTV security camera footage has been critical in the ongoing investigation, although it did not capture the actual attack on Mr Flanagan.
Gardai secured permission to remove a man being held on remand from Mountjoy Prison.
He is being held on remand in connection with a separate and unrelated investigation. He was taken for questioning to Clondalkin garda station and was last night being interviewed about the death of Mr Flanagan.
A file on the matter will be submitted to the Director of Public Prosecutions.
