Police allege a Hyundai Elantra sedan pulled up alongside the car and a man and a woman got out, dragged the woman from her vehicle and forced her into their car before driving off.
While trapped in the sedan, the young woman was allegedly repeatedly attacked and had her credit cards stolen.
Police allege that the car drove to George Booth Drive at West Wallsend – a distance of around 17 kilometres – before it stopped.
One of the alleged attackers, a 38-year-old woman, got out and dragged the 20-year-old from the vehicle and continued to assault her on the street.
While at the home, police allege the woman was forced into the shower and again attacked – this time while being filmed.
Officers from Parramatta Police Area Command were alerted to the footage on social media, prompting the Lake Macquarie Police District to being investigating.
When police arrived at the Windale property, the young woman was being treated by paramedics.
She was taken to Belmont Hospital in a stable condition.
A 37-year-old man and a 38-year-old woman were arrested during a raid on a home in Box Place, Gateshead, at 7.30am yesterday.
During the raid, police seized a Hyundai Elantra sedan which will now undergo forensic examination.
Both have now been charged with a number of serious offences including robbery in company, kidnapping, assault occasioning actual bodily harm, stalking and filming a person in a private act without consent.
The 37-year-old man has also been charged with two counts of contravening a prohibition or restriction in an Apprehended Violence Order (AVO).
They have both been refused bail to appear before Belmont Local Court today.
