Six people have now lost their lives as a result of what is believed to be a feud between two gangs, sparked by a murder in Spain, but with most of the violence taking place in the greater Dublin area.
24 September 2015
The murder of Gary Hutch in Spain was the first in this spate of killings. At the time, gardaí expressed concern that there could be retaliations. They suspected his death was linked to a dispute with a criminal gang. Hutch, a criminal from a well-known Dublin family, was a nephew of Gerard Hutch, aka the Monk.
Hutch had links with an organisation led by convicted drug dealer Christy Kinahan, which Spanish police say controls property and assets worth hundreds of millions on four continents. However, he was believed to have fallen out with this group before his death.
5 February
David Byrne was killed in an attack at the Regency Hotel in Dublin, during a weigh-in for a boxing match. Gardaí believe six men were involved in the attack, three in SWAT-style uniforms armed with automatic weapons.
Two other men, one disguised as a woman and wearing an auburn wig, the other a stocky man in a beige cap, carried hand guns in the attack. Gardaí said they suspected the shooting could be related to the murder of Gary Hutch.
Gardaí believe the main target of the Regency Hotel attack was Daniel Kinahan, who escaped unhurt. They believe Byrne, and the two other men that were injured, were aligned to an international drugs cartel from Spain.
8 February
Eddie Hutch, a brother of the Monk, was shot dead three days after the Regency Hotel attack, in what gardaí believe was retaliation for the death of David Byrne. The 59-year-old taxi-driver was killed when a gang of four men burst into his home on Poplar Row in Ballybough on Dublin's north inner city and shot him several times.
His family pleaded for no retaliation over the murder and called for the cycle of violence "to stop now" amid a heavy garda presence at his funeral.
23 March
Noel Duggan, another Hutch associate, was shot dead as he sat in his car outside his home at the Old Mill estate in Ratoath, Co Meath. Gardaí described the murder as a barbaric act.
14 April
Martin O'Rourke, a father of three from Cypress Hill, was shot dead in Dublin's inner city in what gardaí believe was a case of mistaken identity.
The 24-year-old tried to run away but was shot several times by a gunman dressed in dark clothes, who then cycled away. Gardaí do not believe Mr O'Rourke was the intended target, and are treating his death as the fifth killing in the Hutch-Kinahan feud.
25 April
Michael Barr, originally from Co Tyrone but living in the north inner city area, was shot dead last night, and is thought to be the latest victim of the feud. There is suspicion that Barr was connected to the Hutch faction and was involved in the shooting at the Regency Hotel.
Gardaí were investigating him and last week raided his home.
24 May
A man was shot and seriously injured in Dublin's north inner city in what is believed to be connected to the ongoing feud.
The shooting happened at around 10am this morning in the Avondale House flat complex in North Cumberland Street.
