A woman has been arrested on suspicion of attempted murder after three children – one of whom was a baby – were seriously injured in a stabbing in Huddersfield.

Police officers were sent to a home on Walpole Road in the West Yorkshire town at 8.02am this morning after a “report of concern” from the ambulance service.

Two boys, one aged three months old and the other aged two years old, and a girl aged four were found with serious injuries at the house.

The injuries are believed to have been caused by a bladed weapon.

The three-month-old baby is still being treated in hospital for non-life-threatening injuries as is the four-year-old girl.

The two-year-old boy is in a serious but stable condition.

The arrested woman, who is aged 34, was also taken to hospital with serious injuries.

DCI Sam Freeman of the Homicide and Major Enquiry Team (HMET), said: “We continue to carry out extensive enquiries into this incident which resulted in three children suffering serious injuries this morning.

“A woman continues to be treated for injuries and remains under arrest in hospital. Based on our investigations so far, we are not seeking anyone else in connection with what has taken place.

“Officers continue to support the family involved at what is clearly a dreadful time for them.

“I would like to remind residents that this case involves very young children and ask that their privacy is respected and members of the public avoid unhelpful speculation which can only increase distress for the family involved.”

Chief Inspector Rebecca Calpin, of Kirklees Police, said earlier: “Reassurance patrols are taking place in the local area by officers from the Huddersfield neighbourhood policing team and will be continuing throughout the day as Kirklees officers work to support colleagues from HMET.”

Neighbours spoke of their shock with one saying: “I don’t know the lady but I’ve seen her when I’ve been taking my kids to school and we’d greet each other, she’s good. I was very, very shocked.”

Another Walpole Road resident said: “I just knew (the family) to say hi to – they seem like good people.”

Vincent Jones, 86, who has lived in the street for more than 40 years, added: “I saw the ambulance out there and they were taking a woman away. The ambulance woke me up at about 8am.

“She was wrapped in blankets. There were loads of ambulances and police cars.”

Mr Jones said that while he did not know the family well, he had seen a woman and her small children in the neighbourhood.

“I saw them about, but not to have a conversation with. They would say hello and that’s it,” he said.

“I saw her running up and down with the two children and she had another one recently, about Christmas time.

“Let’s just hope they’re all right.”
