Layla Awod said she had just visited the mother of the Bartholomew Road victim, who she was neighbours with.
Speaking on the Peckwater Estate, she said the mother told her she saw her son lying on the floor as he died.
The mother went to the crime scene after seeing an ambulance and hearing lots of noise, and recognised the jacket of the victim.
“She said (to the police) that jacket looks like her son’s and can she have a look if it’s her son and they refused,” Ms Awod said.
“She called his mobile and it was ringing and that’s when she realised that it was her son, and they refused to let her in.”
Ms Awod said the boy was on his way back home from college when he was stabbed.
