A man has been arrested on suspicion of murdering mother-of-five Sandra Boyd at her family home in Dublin over the weekend.
The 36-year-old died after she was shot at the house at Collins Place in Finglas East in Dublin at around 8:40pm on Saturday.
She was taken to the Mater Hospital, where she was pronounced dead a short time later.
This morning, Gardaí arrested a man in his 20s in the Dublin region on suspicion of murder.
He is being held at Finglas Garda Station.
Gardaí are investigating whether Ms Boyd was accidentally shot with a gun that brought into her family home.
A post-mortem has now been completed and investigators are appealing for witnesses who were in the Collins Place area of Finglas at around 9pm on Saturday to come forward.
On Newstalk Breakfast earlier, Sinn Féin Councillor for Ballymun-Finglas Anthony Connaghan said the community is “shocked, saddened and numb with grief” after teh death.
“The details were kind of sketchy as they came out but now, we are learning it may have been accidental […] and unfortunately, she has lost her life,” he said.
“Straight away what I heard from people was, they were sobbing, numb and they just couldn’t believe it – no-one could.
“A mother there with five kids in the house. It is just shocking and no one can believe it at this stage.”
He said weapons are readily available in the area and people are scared they could find themselves caught up in the crossfire of feuding gangs.
