A teenage girl has denied that she kicked a dying schoolboy in the head after he was stabbed at an Underground station.
Sofyen Belamouadden, 15, died after being attacked by a gang from another school in front of horrified passengers in the Victoria station ticket office in London in March 2010.
Victoria Osoteku, 19, of Deptford, south London, said she joined a crowd of youths as they ran across the road but did not know what was happening.
As she reached the bottom of the steps, she sensed that somebody was being attacked.
The prosecution alleges she was party to the attack as part of a pre-arranged fight between two groups of rival school students.
Up to 20 youths were armed with knives and a Samurai sword. They chased Sofyen down some steps and into the ticket hall.
She was said to have bought a set of knives at lunchtime and joined in the attack after school by kicking Sofyen as he lay bleeding on the floor.
Osoteku, who was 18 at the time, denies murder at the Old Bailey.
She said she saw one youth with a knife before the crowd around the victim parted and she could see a boy on the ground.
"I just went to see if he was OK and I nudged him with my foot to see if he was OK," she wept.
"He didn't move. I looked down and then I ran off. I panicked. I did not know what to do ."
Sofyen was stabbed nine times to the body and suffered wounds to his heart, a lung and major blood vessels.
The trial was adjourned to tomorrow.
