A 16-year-old boy is in custody after a woman and a young girl were found stabbed in a family tragedy in Queensland.

Emergency services went to a home at Rosewood, west of Brisbane, on Thursday night, where they found the woman, 39 and the girl, 11, with a number of wounds to the abdomen.

Another child also living at the home escaped without injury and is being cared for by relatives.

Despite being critically injured, one of the victims called emergency services to raise the alarm, Detective Inspector David Briese told reporters on Friday.

Both have undergone surgery and remain in hospital in a critical condition.

“They have suffered significant injuries … what I do know is that the actions of the first response officers that attended have certainly gone a long way to keeping both people located there alive,” Det Insp Briese said.

A 16-year-old boy who lives at the home was taken into custody, and a bladed weapon was seized at the property.

“There was a potential weapon located … the scene is currently under police guard and will be assessed during the next day or two by scientific officers,” Det Insp Briese said.

Investigations are continuing.
