A man has been arrested and questioned in relation to the murder of Siobhán Kearney in south Dublin four months ago.
The Garda Press Office yesterday confirmed that a man was arrested and questioned on Tuesday in relation to the murder. He was released the same day without charge.
A Garda spokeswoman added that the investigation into Ms Kearney's death was ongoing, and a "file was still being prepared for the Director of Public Prosecution (DPP)".
The arrest was made under Section 4 of the Criminal Justice Act.
Ms Kearney's body was discovered in a bedroom of a house at Knocknashee, Goatstown, Dublin, on the morning of February 28th. Gardaí were alerted by a relative who had arrived to visit her. Her three-year-old son Dan was in the house at the time.
Ms Kearney (38) had been strangled with a flex from a vacuum cleaner.
She had lived in Dublin for parts of the year with her husband, Brian, and her son. The couple owned a hotel in Majorca and spent most of their time there.
Ms Kearney had been locked into an upstairs bedroom and gardaí believe the scene was altered to make it appear as if she had taken her own life, which gardaí initially believed.
However, a postmortem found that Ms Kearney was strangled. Detectives investigating the murder believe her killer was known to her.
