Police are hunting for an 11-year-old suspect believed to be involved in the stabbing of a 14-year-old boy.
The teenager was first attacked in Salisbury Road, Gravesend, by two older boys.
One punched the victim before two more arrived and also attacked the teen, with one of the suspects producing a knife before it was used to stab the victim in his leg.
Two of the offenders then left on a pushbike while the other two ran away, leaving the victim injured. He was taken to hospital to be treated for leg injuries, consistent with a stab wound. He has since been discharged.
The four offenders were white. One is between 11 and 12 with blonde hair and is around 4ft 4ins. He was wearing a blue hooded coat with a backpack and black trousers.
A second suspect is around 16 to 18 years old with ginger/blonde wavy hair, of medium build and around 5ft 11ins. He was wearing a silver hooded coat and black trousers.
A third has blonde hair, is of a slim build and is also around 5ft 11ins.
The fourth has dark short hair and was wearing black trousers. He is around 5ft 5ins and aged between 15 and 16.
