Officers from the force were called around 10.20 p.m. after the victim, a man in his twenties, was discovered with a single stab wound in an alleyway near Manor Close.
Two men wearing balaclavas approached the man from behind and threw him from his bike to the ground. He was then thought to have been dragged along the ground and stabbed.
Soon after, two men were seen fleeing the scene towards the recreation area near Sangers Walk.
The victim was taken to the hospital, where he is in critical but stable condition.
