Two men are being questioned over the murder of a man beaten and stabbed to death.
Gerard Delaney was killed in Cork city last December when an ongoing feud between two families descended into a pub brawl and street fight.
Gardai said the row broke out inside the Manhattan bar on Lower Friars Walk before it spilled out on to the street and at one stage involved more than 20 members of the Delaney and Crinnion families.
The 51-year-old victim had been babysitting his grandchildren when a relative phoned and asked him and others for back-up.
Mr Delaney, from Lakelands Crescent in the Mahon area of the city, was beaten, kicked in the head and stabbed in the head and back.
A suspect in his late teens and another in his early 20s have been arrested in the Togher area. They are being detained at Togher Garda Station under Section 4 of the Criminal Justice Act 1984.
It is understood Mr Delaney, a father-of-two, did not have convictions for serious crime and had tried to keep himself out of a feud involving his relations and the Crinnion family.
