Gardaí are questioning a man arrested in connection with the shooting of Eddie Hutch Senior in Dublin.
The 59-year-old - who was a brother of Gerry "The Monk" Hutch - was shot at his home on Poplar Row in February 2016.
It happened three days after the Regency Hotel shooting in which Kinahan associate David Byrne was killed.
Gardaí believe he was targeted as part of the Hutch-Kinahan gangland feud.
This inter-family feud began in 2015, with the shooting of The Monk's nephew Gary Hutch in Spain.
In a statement, Gardaí say they've arrested a man in his 40s in connection with the shooting of Mr. Hutch Senior. He's being held at a garda Station in Dublin.
