Gardaí in Cork are treating as suspicious the death of a man in his 60s who was pronounced dead when he arrived by ambulance at Cork University Hospital this evening.

The man's brother, who was also in the ambulance, is described as being in a stable condition.

Both men were being brought by ambulance to CUH at around 6.30pm this evening, after gardaí in Macroom were called to a dispute between three men at Aghabullogue, near Rylane.

The two elderly brothers needed hospital treatment but their injuries were not thought to be serious.

However it is understood that one of the brothers may have sustained a heart attack while in the ambulance on its way to Cork.

He was pronounced dead on arrival at the hospital. A HSE spokesman says his brother is in a stable condition.

The area where the dispute is understood to have taken place has been preserved, pending the outcome of the post mortem examination.
