The only suspect in the murder of a 26-year-old mother presented himself at a Garda station at around 5am yesterday.
The Irish Independent has also revealed that Gardaí had been investigating a number of alleged domestic violence issues concerning the woman at the centre of the tragic case.
The arrested man, a Romanian national aged in his 30s, was still being questioned last night at Ashbourne garda station after he went to a Co Louth station shortly after the knife attack in which the victim was stabbed at least once in her home.
The man, who is well known to the victim, was last night being detained under Section 4 of the Criminal Justice Act, 1984.
The young woman found dead at her rented Co Meath home yesterday is a Romanian national but had been living in Ireland for a number of years.
Larisa Serban, who was in her 20s, was found fatally stabbed in her home in the townland of Rathmore, near Athboy.
Ms Serban and her family are originally from Romania but have lived in Ireland for a number of years.
She had been living at various locations in counties Meath and Westmeath in recent times.
It is understood that officers were alerted to the situation by an emergency call from a female and it is understood that a number of people were in the house when the fatal assault happened.
Gardaí at Kells are now investigating all of the circumstances surrounding the fatal assault.
