Gardaí investigating the murder of Derek Coakley-Hutch have arrested a man.

The 27-year-old had been sitting in a car parked at the Bridgeview halting site, beside Cloverhill Prison, when he was shot on January 20th last year.

He was believed to be a victim of an ongoing gangland feud in Dublin.

Gardaí arrested one man aged in his mid-20s on Friday morning in connection with the murder.

He is being detained at Ronanstown Garda Station under Section 50 of the Criminal Justice Act.

He is the third person to be arrested in relation to this investigation.
