ONE OF three teenage boys charged with the sexual assault of a 15-year-old girl in western Sydney is believed to be a former child soldier from west Africa, court documents reveal.

The 17-year-old Liberian-born boy, who cannot be named, was refused bail when he faced Parramatta Children’s Court yesterday, just over two months after the girl was allegedly assaulted by three teenagers at a home in the western Sydney suburb of Mt Druitt.

Court documents show a staff member at a youth care organisation believes the boy, who has no parents in Australia, “was a child soldier of war”.

The 15-year-old girl allegedly had her drink spiked before being gang raped by the three boys.

The girl was allegedly attacked by the trio, aged 15 and 17, at a Mount Druitt home linked to the 15-year-old in May.

She had attended the home with some girlfriends who knew the 15-year-old boy and was allegedly set upon after the girls had left late on Saturday, May 21.

The 15-year-old boy was arrested a day after the rape and charged with four counts of aggravated sexual intercourse with a person aged 14-16. He has been refused bail to reappear today.
