Update 1.32pm: A knife has been recovered in the investigation into an attack on a woman in Dublin last night.
Gardaí believe the knife was used during the attack, according to RTÉ.
Update - 10.52am: The Garda Technical Bureau is examining the scene in Dublin where a woman was killed last night.
The 37-year-old French woman died, and her 35-year-old Brazilian partner is in hospital, after a suspected domestic incident.
The scene at the Dorset Square Apartments remains sealed off ahead of an examination by the State Pathologist.
Local Councillor Neil Ring says it is an upsetting incident to see.
He said: "In this particular area, Dorset Square, it is off the beaten track, so to speak. There seems to be, from my knowledge of the area, a lot of foreign nationals live there.
"They keep themselves to themselves and in a way that's sad, because nobody heard anything or there doesn't seem to be any neighbours who have heard anything at all."
