A man in his 30's is due to appear before a special sitting of Enniscorthy District Court tonight where he will be charged in connection with the death of Ben Carolan.
Mr Carolan (62) died at his home at St Georges Place, in the city centre.
Gardaí went to Mr Carolan's address on Thursday last after neighbours expressed concern that he had not been seen that day.
He was discovered in his bedroom and taken to Dublin City Morgue where a post mortem was carried out. It is believed he had sustained injuries to the throat.
