A man has been arrested by gardaí investigating the murder of Dublin woman Rachel O'Reilly.
Rachel: family believes she knew her attacker
The man (35) was detained in Crumlin at 7am and taken to Balbriggan Garda Station in north Co Dublin for questioning.
A Garda spokeswoman said the man was being held under Section 9 of the Offences Against the State Act on suspicion of withholding information.
He can be held for an initial 24 hours and up to a maximum of 72 hours if the time is extended.
Last week, gardaí exhumed the body of Ms O'Reilly, suspecting a note left in her coffin could offer a new lead.
The mother-of-two sustained several blows to the head and was found by her mother at her home at Baldarragh, near Naul village, on October 4th, 2004.
There were no signs of a struggle between Ms O'Reilly and her attacker. The house had been disturbed, indicating a possible break-in, but the dead woman's family have said they believe this may have been staged and that Ms O'Reilly was probably killed by somebody known to her.
Money in Ms O'Reilly's purse was untouched.
