Police are questioning a woman after a young mum was savagely kicked to death at a Halloween party at her mother's home.
They arrested a woman who they believe was involved in a row with Bernadette Cash, 20, who was found dead the following morning.
The mum-of-one lay dying as party-goers fled the house in Blanchardstown, West Dublin.
It is understood married Bernadette, who is believed to be separated from her husband, regularly stayed at the detached house in the quiet cul-de-sac and had thrown a party there on Wednesday night.
The party turned to tragedy when she was found dead and alone in the house by friends on Thursday.
Detectives believe Bernadette was attacked during the party before being left dead or dying on the living room floor.
Her grief-stricken mother Brigid rushed to the scene yesterday and screamed: "Who would do this to my daughter?"
She later sobbed: "She was a beautiful young girl, we are devastated."
A neighbour told the Irish Mirror: "Her mum arrived about 10 minutes after I called the police and she just jumped out of a taxi and started screaming 'where's my daughter, what happened to my beautiful daughter?'
"It was terrible, I'll never forget her screams, she was in pieces and no one could comfort her."
Supt Dave Taylor said: "On arrival at the scene, gardai discovered the body of a female in the front sitting room with obvious head injuries.
"We are appealing to anyone in the Warrenstown Walk area who saw any unusual or suspicious activity between 5pm yesterday evening and 11am this morning.
"We aware there was a social gathering at this house and there would have been a lot of comings and goings throughout the night and we're looking to speak to anyone who was at the party.
"A number of people have come forward and been very, very helpful to our investigation."
