The 30-year-old man suffered serious injuries following a blow to the head at about 2.20am on Sunday morning near the Grafton Bar on Oliver Plunkett St.
The man, who lives in the Gurranabraher area of the city but is believed to be from the Middle East, made his way home but fell ill and was rushed to Cork University Hospital where he underwent brain surgery.
The assault is believed to have happened during some sort of melee. Supt Barry McPolin, who is leading the investigation, said the man was “critical but stable”. Gardaí are trying to establish whether the head injury was a result of the blow or if it was caused when the man fell to the pavement.
Supt McPolin said they were following a definite line of inquiry but that they were also appealing for witnesses.
Separately, a woman was assaulted on the South Mall in the early hours of yesterday morning and had to receive treatment for her injuries in hospital. The woman’s phone was stolen during the attack which gardaí said was not sexually motivated.
The woman, a foreign national, was assaulted at 5.30am. Gardaí believe it was a single individual that carried out the attack.
