A garda spokesperson said: “Gardaí attended the scene of an assault that occurred on Grattan Bridge, Dublin 1 at approximately 12:40am today, Saturday, August 14 2021.
“One man, aged in his 20s, was conveyed to St James’s Hospital for treatment of non-life-threatening injuries sustained during the incident.
“No arrests have been made. Investigations are ongoing.”
The athlete’s attack comes just weeks after he represented Ireland in the Tokyo 2020 Olympic Games.
However, while he had hoped for a gold medal, Jack was left heartbroken after his legs went to jelly during his contest against Argentina’s Lucas Guzman.
Following the tense contest, Jack admitted that he was “devastated” over his performance.
He added: “My legs went to jelly, something just didn’t click”.
