Gardaí have released three people without charge in relation to the ongoing investigation into the murder of Patricia O'Connor.
A 73-year-old man and two women - one aged 19 and the other aged 38 - were arrested yesterday and held as part of the investigation.
A man previously arrested and charged in relation to the case is currently before the courts.
Mother-of-two and grandmother Patricia O'Connor was found dismembered and her remains scattered in the Wicklow Mountains in June this year.
