Four held over drug dealer murder
Three women and one man have been arrested over the murder of a drug dealer by the Grand Canal last week.
Michael Kelly was shot dead in full view of commuters on the Luas near Inchicore in Dublin last Monday.
Gardai said the four arrested people were aged in their 30s to 40s.
They were detained at Pearse Street, Kilmainham and Kevin Street Garda stations under section 30 of the Offences Against the State Act.
