Fergus and Philip Brophy got into difficulty yesterday.
A post mortem's due to be carried out this morning on the bodies of two Laois brothers who drowned in a quarry in Tipperary.
42-year-old Fergus Brophy and 34-year-old Philip Brophy from Ballybrittas got into difficulty while diving in Portroe yesterday.
Gardaí are treating their deaths as a tragic accident.
The Portroe quarry with its picturesque blue waters is a popular destination for local water sports enthusiasts and currently operates as a dive centre.
The brothers, both of whom were in their thirties, were seen entering the water at about half past midday but got into difficulty at some point between then and half past one. They were said to be experienced divers.
Witnesses said one of the men was seen getting out of the water to raise the alarm after his brother got into trouble...but then returned to help him.
When gardaí arrived both men's bodies had already been recovered by amateur divers at the scene.
Kilaloe coastguard, gardaí and ambulance personnel were among those involved in the operation.
The brothers' remains were taken to Limerick University hospital where a post mortem will be carried out this morning.
