A Dublin man has gone on trial accused of stabbing another man to death following a fight outside a pub in Ballyfermot.

Craig O'Halloran with an address at Colepark Road, Ballyfermot denies murdering Kevin Kenny on Sarsfield Road on July 31st, 2011.

Opening the case, the prosecution has told the jury they will hear evidence that the accused Craig O'Halloran was at Ruby Finnegan's pub on the night of the stabbing.

Kevin Kenny - the deceased - and his brother Stephen were among one of two groups that arrived at the bar just before 9pm.

Within ten minutes there was a fracas outside - which was caught on CCTV.

It is alleged the Kenny brothers chased a man up Sarsfield Road and that they in turn were chased by Craig O'Halloran who is accused of stabbing Kevin Kenny a number of times.

The 32-year-old electrician returned to the front of the pub where he collapsed. He was later pronounced dead in hospital.

Craig O'Halloran denies murder. The trial is due to last until the end of next week.
