A special mass has taken place for Karol Rozycki, the baby who lost his life in Killarney on Saturday evening.
The 11-month-old boy was found dead at an apartment in the town.
A Polish man in his 30s, who is believed to be a relative of the baby, was taken from the scene on Saturday, having suffered serious injuries.
The mass at St Mary's Cathedral in Killarney was celebrated by both Fr Piotr Delimat, the Polish chaplain seconded from the Archdiocese of Kraków serving the Diocese of Kerry, and Fr Kieran O'Brien, Radio Kerry report.
The Mass was held in the absence of Baby Karol's body; his funeral is to take place in Poland at a later date.
Baby Karol's mother, Anna, was present at the service and Fr O'Brien said he hoped people's sympathies would help lighten her burden.
He also spoke about how Baby Karol brightened up his family's lives in his short 11 months.
Fr Delimat said Karol's death had brought together the Irish and Polish communities in Killarney.
