A judge has denied bail to a 15-year-old boy accused of being part of a network planning terrorist acts and who claimed to be a friend of another teenager charged with stabbing a Sydney bishop.

The attack on the bishop last month triggered an investigation that led to the arrests of six teenagers, aged 14 to 17, who were charged last week with a range of offences including conspiring to engage in or planning a terrorist act. All remain in custody.
