A woman has been arrested by detectives probing the suspicious death of a mother-of-one found with suspected head injuries after a party.
The body of the 20-year-old was discovered in the sitting room of her mother's home in a housing estate in Mulhuddart, west Dublin.
The victim - named locally as Brigid Bernadette Cash - is a married and a member of the Travelling community and has a two-year-old son.
Detectives have appealed to anyone who was at a party in the property on Warrenstown Walk overnight to come forward.
They have arrested a woman, also aged in her 20's, in connection with the incident.
She can be held for up to 24 hours at Blanchardstown Garda Station for questioning.
The alarm was raised at 10.40am after paramedics made the grim discovery at the address.
The victim's mother, also called Brigid, is a tenant in the rented semi-detached house but was not home at the time and her grandmother was caring for her son.
Deputy State Pathologist, Dr Michael Curtis, and forensic officers examined the scene during the day.
A post mortem is being carried out at Connolly Hospital to determine the exact cause of death and direction of the case, which is expected to be upgraded to murder.
Councillor David McGuinness said neighbours are shocked.
"A lot of people are very upset and are looking for answers," said the Fianna Fail representative.
"Blanchardstown in a large place with over 100,000 people, but we don't have girls in their 20s being found dead in their homes.
"People are shocked at the news and are appealing for people to contact the guards with any information and tell them what happened.
"They need assurances that while it's a tragedy, that the case is being handled."
Socialist Party councillor Ruth Coppinger said the killing highlights the need to tackle violence against women.
"Violence against women is epidemic," she said.
"It's really something that has to be openly discussed more in society.
"I don't know the circumstances of this case, but it was in her home so presumably it's someone known to her. She wasn't walking home from somewhere when attacked.
"The level of violence being used against women and accepted by women is a huge issue.
"It's really scary."
Labour councillor Mary McCamley, who lives near the scene, described the Warrenstown area as a lovely estate.
"It's a quiet, settled place and the people are lovely," she added.
