The murder trial of 15-year-old Woolwich schoolboy Tamim Ian Habimana is continuing at the Old Bailey.
Five youths are accused of killing the Harris Academy Greenwich student as part of a revenge attack.
The prosecution told the jury that Tamim was attacked with a knife, an umbrella and a rounders bat and could not be revived after he collapsed. His death by stabbing left the Woolwich community shocked and distressed.
The five defendants deny all charges.
