A second man has been arrested in connection with the murder of Eddie Hutch in Dublin.
Gardaí investigating the gunning down of the taxi driver say they detained a man in his twenties in the city this evening.
Earlier a man in his thirties was arrested as part of inquiries earlier today.
Both men are detained under section 50 of the criminal justice act.
Several people have died in shootings in the capital in the past couple of months as part of the Kinahan-Hutch gangland feud.
