An employee at a barber shop is set to contest allegations that he, along with three others, sexually assaulted a teenage girl in what police describe as a prolonged gang rape incident.

According to reports, the young man requested a ride to a park in a nearby suburb, with the girl believing he would exit the vehicle once they arrived.

However, upon reaching the park, two additional males allegedly entered the car and proceeded to assault her as well.

A fourth individual later joined in another vehicle, and authorities claim the assaults continued as the girl was driven around for a total of six hours.

The 16-year-old, identified as the alleged leader of this incident, faces charges including 19 counts of sexual assault and five counts of sexual touching.

He remains before the courts.
