PATROLLED

The jury heard how Walker had returned to his flat in Southampton after shopping with his mother when he passed the girls on the building's stairs.

One touched his shopping bag before verbally abusing him and telling him he resembled Harry Potter.

The outraged Walker saw red and came back downstairs with a bottle full of water and threw it on the girls.

He then went back into the flat and re-emerged with a vegetable knife before walking to a local park - aware the girls would follow him.

Walker then lost his temper, stabbing Leah in the face, who then started bleeding profusely.

He attacked Emma, flooring her with a series of punches and kicks, before smashing her head against a fence, shouting "die, die".

sounds like self defense to me
