Three people have been arrested after a young woman was allegedly kidnapped, bundled into the boot of a car, driven to a historic Sydney bridge and thrown into the Hawkesbury River on the weekend.

Three of those behind bars have been charged with attempted murder and other offences including aggravated kidnapping.

The 19-year-old victim has told police she was driven to the seven-metre high Windsor bridge in the early hours of Sunday before a group of people threw her into the river below.

After surviving the fall, she swam to the riverbank and alerted police. She was taken to Nepean hospital for treatment.

New South Wales police allege the victim was kidnapped on Saturday night in Campbelltown before being driven to Windsor, which is 60km away.

Detectives arrested a 22-year-old man in Windsor on Wednesday night on charges including attempted murder, aggravated robbery and wounding a person with intent to cause grievous bodily harm.

A 19-year-old woman and a 17-year-old girl had previously been charged on Tuesday and Wednesday afternoon, respectively, with attempted murder, aggravated kidnapping and robbery with wounding.

On Thursday morning, a 16-year-old boy was arrested at a home in Wallacia. He has been taken to Windsor police station and is assisting detectives with their inquiries.

Investigators do not expect to make any more arrests. They say all five people were known to each other.

The alleged victim’s boyfriend told Fairfax Media she was still distraught while her sister said she had been “bullied for her appearance”.
