A group of people then returned to her house, he said.
"At some point everyone has left her property. She also left the house a short time later and went with Jamie Ginns in his vehicle. He then took her unwillingly to another property, where she was seriously assaulted and tied up with a black power cord.
"She managed to escape from the house, where she was found outside by neighbours who raised the alarm."
By Friday night, police were hunting for Ginns in their inquiry into the kidnapping, Mr Anderson said.
"We now know that he had left Tokoroa by 2pm on Friday afternoon, and only returned to the area on Saturday morning just before the shooting occurred."
Mr Anderson said the victim had requested that no further details about her attack are released.
Police had not been able to speak to her until late on Saturday afternoon because of the extent and nature of her injuries, he said.
"There was a great deal of work to be done on this case alone. When police became involved, we knew very little about what had transpired, apart from the fact that a woman had been assaulted and was found at a house which she had no connection to."
The victim's father arrived in Tokoroa about midday yesterday from the Far North to look after his distressed daughter and spoke to police.
"I'm going to meet up with her - I think she's far from all right."
The father said the 20-year-old lived in Tokoroa with her boyfriend, who was not Ginns.
He said his daughter had been tied with piano wire, nearly "strangled and left unconscious".
He did not know whether the 20-year-old knew Ginns. Mr Anderson said Ginns was the only "similarity" between the assault victim and Ms Glassie.
"They [Glassie and the young woman] are not related and they are not sort of associates as far as I'm aware. That's the focus of our inquiry from today onwards really."
Family speaks out
The family of the Tokoroa woman shot on Saturday has defended the Waikato town as a "loving community", while the 32-year-old remains in a critical condition in Waikato Hospital.
Matakapua Glassie was chased for nearly 7km on State Highway 1 by her former partner, Jamie Ginns, before firing two shots at her outside the Tokoroa Police Station, near where children had gathered for the town's annual Christmas parade.
Ginns, 32, was later found dead in his car in a forest near Rotorua.
Police believe a second woman, who was found hog-tied on a Tokoroa driveway the day before the incident, had been kidnapped by the man, and may not even have known him.
Ms Glassie - aunt of child abuse victim Nia Glassie - remains in a critical but stable condition in Waikato Hospital.
A family spokesperson, who would not be named, thanked those who had helped Ms Glassie after she was shot, particularly the staff at Tokoroa Hospital.
"If it wasn't for their good work, who knows what would have happened to Mata?" they said.
The family asked that the media respect Ms Glassie's privacy.
"Tokoroa is a loving community, it has a wonderful family atmosphere. Mata has lived there all her life and has many friends and family who are helping her. She is a private person and would like to be left alone to rest and recover."
The family also wanted to convey their condolences to the Ginn family.
"We don't hold grudges our family. We know they are grieving too."
Police expect their investigation to continue until the middle of this week and said they would not know whether drugs had been a factor until learning the result of Ginns' autopsy - to be carried out tomorrow.
A full picture of the shooting emerged yesterday when police confirmed that motorists travelling between Taupo and Tokoroa had earlier seen Ginns fire two shots as he chased Ms Glassie's vehicle from the Kinleith turn-off along the state highway right to the Tokoroa police station in Lodge St.
Emergency services received calls about the shots and one motorist followed the chase to the end. Ms Glassie's sister, visiting from Australia, was in the car as well.
Detective Inspector Tim Anderson said: "We've spoken to witnesses who have confirmed that [the on-road shooting]. They thought it was a tyre blowout at first and they turned around and saw him leaning out the window with a shotgun."
Ms Glassie made it to the police station, but Ginns shot her in her car.
While people rushed to her side, Ginns fled. Police are confident the body they found near his car in Mamaku Forest near Rotorua eight hours later is Ginns.
New details have also come to light about an incident at 6.30am on Friday at Ginns' house in Dalmeny St, which police say he still shared with Ms Glassie. It was earlier reported that neighbours found a young woman hog-tied in the driveway.
The woman was taken to Hamilton by police who feared for her safety while they hunted Ginns.
Her father arrived in Tokoroa about midday yesterday from the Far North to look after his distressed daughter and spoke to police.
"I'm going to meet up with her - I think she's far from all right."
The father said the 20-year-old lived in Tokoroa with her boyfriend, who was not Ginns. He said his daughter had been tied with piano wire, nearly "strangled and left unconscious".
He did not know whether the 20-year-old knew Ginns. Mr Anderson said Ginns was the only "similarity" between the assault victim and Ms Glassie.
"They [Glassie and the young woman] are not related and they are not sort of associates as far as I'm aware. That's the focus of our inquiry from today onwards really."
Yesterday afternoon, police had yet to interview the female victims or a man who was with Ginns when he sped from police after the Dalmeny St assault on Friday.
Officers yesterday spoke to another man who they believed was central to the assault investigation, but Mr Anderson said he was not a suspect.
After fleeing Dalmeny St, Ginns drove to an old forestry worker's house in Thompson St and pleaded to borrow a white car. This was the vehicle Ginns used in a high-speed chase and was the car his body was found near.
A man at the Thompson St house, who called himself a "family friend", said the occupants had not seen Ginns for "months and months" until he arrived asking for the car.
He said a 32-year-old who lived at the house had worked "in the bush" with Ginns about 10 years ago. "It [the crime] is nothing to do with him - it's just one of those unfortunate circumstances by association."
