The man accused of choking an 11-year-old Canberra girl unconscious has now been charged with sexually assaulting the child after police allegedly found "disturbing" electronic evidence.
Anthony James Kenyon, 23, has been in custody since February, when he was arrested after allegedly knocking the girl off her bike as she rode through Fadden Pines on her way home from school.
Kenyon sat in the dark on Monday at the Alexander Maconochie Centre, where the lights went out as he appeared in the ACT Magistrates Court via audio-visual link.
