Two boys have been arrested in connection with the murder of 10-year-old London schoolboy Damilola Taylor.
British police say a 13-year-old and a 14-year-old have been detained at addresses in Peckham in south-east London.
The boys have not been detained before and the arrests bring the total number so far to 15.
Both suspects in custody are black youths.
The child bled to death after being stabbed on his way home from an after-school computer class in a library in November.
The youngster had only recently arrived from his native Nigeria. His mother believed he was being bullied at school.
Police have made a number of appeals for help in tracing three boys who were seen near to a stairwell where the child collapsed on a north Peckham estate. PA
