A man has been arrested over the double murder of drug-dealing brothers in west Dublin.
Kenneth and Paul Corbally were gunned down in their car in a gangland hit in June.
The man, in his early 30s, was detained in a morning raid in the city.
He was taken to Lucan Garda Station where he was being questioned under section 50 of the Criminal Justice Act.
The Corballys, aged 32 and 35, were known drug dealers from the Ballyfermot area.
They were shot dead in their car on June 28 on the Neilstown Road, Clondalkin and a 14-year-old boy who was sitting in the back seat was wounded.
