DETECTIVES hunting the killer of a young father in a gangland-style shooting have arrested a man.
Darren Falsey (37) was shot and killed just minutes after returning to his home in Carrigaline, Co Cork on August 3, 2011, from a social trip to Cork city with his partner.
He was shot as he answered the door to his home at Ashbourne Court just off Ferney Road in the south Cork town.
Gardai today (Wednesday) arrested a 28-year-old man at his home in Carrigaline for questioning in relation to the killing.
He was taken to Togher Garda Station.
The arrest is the sixth detention in relation to the murder and follows the arrest of a man in Limerick Prison for questioning two weeks ago.
The other individuals arrested, all of whom are in their 20s and 30s, were subsequently released without charge.
Mr Falsey, who was a suspected drug dealer, had received a bullet in the post several weeks before the killing as a grim warning believed to be linked to an outstanding debt.
In follow-up searches after the shooting, gardai discovered €30,000 in a freezer in a storage garage used by Mr Falsey in nearby Riverstick.
Two months after the killing, gardai recovered a handgun as part of searches linked to organised crime in the Munster area.
The searches were focused on dense woodland in the north Cork area and detectives believe the handgun was the weapon used in the Falsey shooting.
Gardai have been examining DNA and fingerprint samples from a number of individuals in the Cork area as part of the Falsey investigation.
Detectives stressed that their investigation is now at a critical stage and renewed their appeal for anyone who was in the Carrigaline area on August 3, 2011, to contact them.
The victim is believed to have been under surveillance by his killers who patiently waited until he had returned from a shopping trip to Cork city with his partner and her children.
When the young woman left to go to Carrigaline town, the killer walked to the front door and shot Mr Falsey three times when he answered the front door.
His shocked partner found him lying dead in a pool of blood when she returned to the rented house.
Mr Falsey was a former schools rugby player and is understood to have been threatened repeatedly in the weeks before his death over an outstanding debt.
