A BROTHER and sister will appear in court this morning charged with the murder of 63-year-old Thomas Horan.
Gardai had questioned the 27-year-old man and his 37-year-old sister throughout the day about the murder of Mr Horan at his sheltered accommodation home in Ringsend, south Dublin.
The suspects were arrested on the northside of the city on Wednesday afternoon and taken for questioning to Donnybrook and Irishtown garda stations.
Their period of detention was extended yesterday morning.
Earlier it emerged that Mr Horan had visited his estranged wife to check in with her on the day he was killed.
Gardai believe that just hours after he visited his wife, Mr Horan was beaten and kicked to death by callers to his apartment.
He had allowed them into his apartment home at Cambridge Court, off Cambridge Road, in Ringsend.
A post-mortem by State Pathologist Professor Marie Cassidy confirmed that he had died as a result of internal injuries.
Meanwhile, a relative of Mr Horan's has revealed how his elderly wife was one of the last people he saw.
Originally from Mullingar, Mr Horan married a woman from south Dublin in the late 1970s and they settled down in Ranelagh, near where he worked as a domestic servant at the Marist Fathers regional office in Milltown.
The family source said although the couple were separated "they still had great contact with one another".
"Even on Sunday, Thomas called in to make sure everything was alright. He would always check to make sure that she had enough food in and enough of everything."
They described Mr Horan as "a very simple person" who "thoroughly enjoyed his music -- his apartment was full of records and CDs."
Gardai said they had made progress with their inquiries since the body was found on the floor of Mr Horan's bedroom around 4am on Monday.
Mr Horan had been living in the Cambridge Court flat for more than three years.
One resident there, Billy Burke, said that the complex desperately need CCTV cameras, saying: "We don't know who's coming in here at night time. The flats across the road have cameras for people who are able-bodied and are able to defend themselves, yet down here we have nothing."
Asked about the lack of CCTV cameras at Cambridge Court, a Dublin City Council spokeswoman said that the local authority "will not comment due to the fact that there is a garda investigation taking place".
The emergency services were alerted when neighbours became concerned after they heard shouting.
Gardai yesterday anybody with information to contact them at Irishtown station, at 01 6669600 or on the confidential line, 1800 666111.
