Teddy bears, tributes and flowers have been left near the scene where a pregnant woman died as police continue to question a man in connection with her murder.

Sarah Montgomery, who was 27, was the mother of two young girls and pregnant with her third child when she died at her home in Donaghadee, County Down.

One of the tributes left outside the house at Elmfield Walk described her as a "beautiful, kind and wonderful mother". Officers are still continuing investigations at the victim's home, which is cordoned off.

A 28-year-old man arrested on suspicion of murder remains in police custody on Monday morning.

The Police Service of Northern Ireland (PSNI) first received a report of the attack at about 14:15 BST on Saturday.

Officers were told an unconscious, seriously injured woman was inside the house at Elmfield Walk.

PSNI officers and ambulance staff responded and paramedics provided medical treatment but Ms Montgomery was pronounced dead at the scene.

A murder investigation was announced on Sunday, with Det Ch Insp Tom Phillips describing it as a "deeply tragic case".

A number of mourners have left flowers and notes paying tribute to the victim.

One of them read: "RIP Sarah – beautiful, kind and wonderful mother. Thinking of you and your family and your two little girls."

The local MP, Alex Easton, said Ms Montgomery's children attended the same primary school as his own grandchild and she was regularly seen on the school run.

"She's been described as somebody who kept to herself and never was in any bother," he told the BBC's Good Morning Ulster programme.

He said he had been speaking to resident in Donaghadee over the weekend and they were still "extremely shocked by what's happened".

Easton described the murder as "wrong and barbaric" and said more action is needed to protect women and girls from attack.

"I think Stormont maybe needs to look at doing some sort of education in our schools - that our children are taught that violence against women is totally wrong," he added.
