Detectives investigating a stabbing in Poleglass on Monday night, arrested a 26-year-old man.
At around 6pm two people, a man and a woman, called at an address in Woodside View and became involved in an altercation with the female resident at the door.
One of the pair stabbed the householder in the abdomen before both fled the scene.
The 35-year-old victim is currently receiving treatment in hospital and we understand her condition to be critical but stable.
Detective Inspector Brian Foster said: “The arrested male was detained by detectives in north Belfast.”
