Gardaí in Limerick believe they have made a major breakthrough in a murder investigation following the arrest of two brothers yesterday.
The arrests came just under a month after the stabbing of a father of five outside a city pub.
Martin O'Donoghue (34), from St Mary's Park in Limerick, was stabbed to death in a violent pub row, which spilled out onto a street in the city on August 9th last.
He was stabbed a number of times and was found in a laneway off Broad Street, in the city centre, bleeding heavily from his wounds.
A post mortem revealed that Mr O'Donoghue was stabbed once in the neck and three times in the abdomen and chest area.
The stabbing took place after a row started inside a pub between a number of people.
It is understood Mr O'Donoghue was pushed out onto the street after the row ensued inside The Pub bar on Broad Street.
A number of weapons were recovered at the scene, including a large knife which gardaí believe may have inflicted the fatal stab wound.
Security video footage from a number of cameras in the area has also been seized by gardaí.
Yesterday morning two brothers were arrested at their addresses on the Dublin Road and St Mary's Park shortly before 8 a.m.
They were being questioned last night Under Section 4 of the Criminal Justice Act.
Up to eight people, including a number of women, have already been questioned about the fatal attack.
The killing was the fourth murder in Limerick since the start of the year.
