A man in his 40s has been arrested in connection with the killing of Eddie Hutch Senior almost seven years ago.
The 59-year-old, who is a brother of Gerry "The Monk" Hutch, was shot dead on February 8th, 2016.
Gardaí believe Mr. Hutch Senior was targetted as part of the Hutch-Kinahan gangland feud.
The father of five was killed at his home on Poplar Row, three days after the Regency Hotel shooting in which Kinahan associate David Byrne was killed.
In a statement, Gardaí say they've arrested a man in his 40s in connection with the shooting, and that he's being held at a Garda Station in the capital.
This inter-family feud began in 2015, with the shooting of The Monk's nephew Gary Hutch at an apartment in Spain.
