The 14-year-old girl who was allegedly gang-raped in a western Sydney park was so traumatised that police had to wait a day before they could speak to her.
The girl was walking a short distance home from a friend's house through Bill Colbourne Reserve, Doonside, when she was approached by a man of African appearance at 11pm (AEDT) on Saturday.
He allegedly touched her inappropriately before he forced her to the ground and allegedly sexually assaulted her on one of the paths in the park.
It's alleged the man's five friends then took turns sexually assaulting her in an attack that lasted about 30 minutes.
Superintendent Gary Merryweather, Blacktown local area commander, said it was a horrendous attack in a quiet residential community.
"Being of such a tender age, she is traumatised to an extent that I can't really describe," Supt Merryweather told reporters on Monday.
"Part of the delay of us getting the information out to the public is because the young girl was in shock.
"Her family are nice people, they're good people ... they're just completely devastated."
The men fled, leaving the girl to walk to a friend's house nearby where police were called and she was taken to hospital.
The men are all described as being of African appearance and aged in their late teens to early 20s and police say people in the community must know the men responsible.
"There's a high probability that they must have said something to someone," Supt Merryweather said.
"If people do not ring and contact the police they are condoning this horrendous behaviour."
Local detectives and the State Crime Command's sex crimes squad, are investigating.
Anyone with information is asked to call Crime Stoppers on 1800 333 000.
