Detectives investigating the murder of a French woman in the capital have arrested a man who is well known to her.
Anne Colomines (37) was stabbed to death at her home in Dorset Square, Dublin, last month.
Her husband, Renato Gehlen (35), also suffered more than 30 knife wounds and was discovered with life-threatening injuries.
He was treated at the Mater Hospital for a number of days and underwent emergency surgery.
Investigating detectives at Mountjoy Garda Station yesterday arrested a man as part of the murder probe. He was detained under section 4 of the Criminal Justice Act and can be held for up to 24 hours.
This man was well known to the victim and is the chief suspect in the murder.
The Herald previously revealed how the suspect admitted killing Ms Colomines immediately after her murder, but claimed that he acted in self-defence.
Gardai were alerted to the incident at around 11.30pm on Tuesday, October 24, as a number of Dublin Fire Brigade crews also rushed to the scene.
Ms Colomines was pronounced dead in the property. A knife, believed to be the weapon used in the killing, was recovered in the aftermath.
Tributes were paid to the finance agent following her murder, with a close friend and former colleague describing her as "kind and fun-loving".
"She was a very kind person. At work, she was very hardworking and always happy to help others," her friend, who asked not to be identified, said.
"I didn't know anyone who disliked her. Anne spent a lot of time volunteering with homeless cats. She loved her cat, Kitty, with all her heart.
"She was quiet and worked a lot but enjoyed going out for dinner with friends. Her friends and her family made her really happy. Anne was such a kind, fun-loving friend who wore her heart on her sleeve. She'll be missed so much."
It is understood that Ms Colomines had been living and working in Ireland for some time.
