Police investigating the death of a pregnant woman in Northern Ireland have made a second arrest.
Sarah Montgomery – a 27-year-old mother-of-two – died at a house in Donaghadee, County Down, on Saturday.
A 28-year-old man, who was arrested on suspicion of murder over the weekend, remains in police custody.
The Police Service of Northern Ireland (PSNI) said detectives have been granted a court extension of a further 36 hours to question him.
On Monday, the force said a 42-year-old woman has also been arrested in Belfast on suspicion of assisting an offender.
Police said both suspects were known to the victim and they are not seeking anyone else in connection with the incident.
Detective chief inspector Tom Phillips said officers were “working at pace to determine the circumstances of Sarah’s tragic murder and need help from people in the Donaghadee and Belfast areas”.
“Did you see or hear anything unusual or suspicious in the Elmfield Walk area of Donaghadee between 1.20pm and 2.20pm on Friday 27 June?,” he asked.
“Did you see a yellow Jeep Avenger in the Airport Road area of the Belfast Harbour Estate, East Belfast between 3.30pm and 4.15pm on Friday 27 June?
“Do you have CCTV, dashcam or phone footage which could be useful in our investigation?
“Even if you think it may not be important, please come forward and speak with us as even very small pieces of information could prove invaluable to us.”
