Gardaí investigating the gangland murder of Noel Roche (27) in Clontarf, Dublin, on Tuesday night are still questioning a man arrested last night in Dublin's city centre.
The man, believed to be the driver of the dark Ford Mondeo car in which Mr Roche was travelling when he was shot dead by passing assailants, has had his period of detention extended.
The extension of 24-hours means he can be questioned until 4pm tomorrow afternoon.
The driver, whose name has not been officially released, is thought to be in his early 30s and is from Crumlin, Dublin. He staggered from the scene of the shooting at about 10.30pm on Tuesday near the Yacht pub on Clontarf road.
Supt Nicholas Conneely said the arrested man was being held for questioning in Raheny under Section 30 of the Offences Against the State Act.
