A 17-year-old boy is in hospital after being stabbed in west London.
The victim was discovered on Richmond Green after the Met Police was called just before 21:55 BST on Friday to reports of a group of males fighting.
He was taken to hospital, where his condition is described as stable and not life-threatening.
It is believed the victim knows who the perpetrators are but does not want to name them for fear of reprisal.
No arrests have been made and officers remain at the scene.
