Five teenagers, including two as young as 13, have been charged with murder after the death of a 16-year-old boy found with severe injuries in Sydney.
The boy was found unresponsive with head and chest injuries in a home in Doonside on Wednesday afternoon.
Four other boys - aged 13, 13, 14 and 15 - and a 15-year-old girl were arrested in the following 24 hours and charged over the assault.
They allegedly took or detained the boy with an intent to gain an advantage.
Murder charges were added on Saturday after the boy died in Westmead Hospital.
All five accused teenagers were refused bail and are due to reappear in a children's court on August 13.
