A FOURTH man has been arrested over an alleged kidnapping at Elizabeth Park on the weekend, with three other alleged suspects facing court on Monday.

Just before 1am on Saturday, a woman called Triple Zero, claiming she had been kidnapped at gunpoint and was in the boot of a car.

She also provided police with vague details of her location.

A short time later, patrols identified and attended an Elizabeth Park house where they located the woman tied up in the boot of a Mitsubishi sedan.

Police then entered the property and located two men and a woman who were all known to the victim and arrested them.

A 33-year-old Elizabeth Park woman, 33-year-old Valley View man and a 39-year-old Para Hills man were all charged with kidnapping, aggravated threats to kill, aggravated assault causing harm, aggravated assault and illegal use.

The trio faced court on Monday, where police alleged the victim had met one of the accused at Para Hills earlier in the evening before, where she was threatened with a gun before being forced to drive to the property at Elizabeth Park.

It is then alleged the victim was taken inside and assaulted before being tied up and placed in the boot of the Mitsubuishi.

On Monday night, police arrested a 26-year-old Clearview man at a Salisbury Downs address without incident.

He was also charged with kidnapping, aggravated threats to kill, aggravated assault causing harm and aggravated assault.

He was refused bail and appeared in the Elizabeth Magistrates Court yesterday – after The Bunyip’s print deadline.

Following the alleged incident, the victim was taken to the Lyell McEwin Hospital and treated for several injuries, including a fractured eye socket.

Police have appealed for anyone who may have seen a black Mitsubishi Magna – registration WUA 612 – driving erratically in the northern suburbs between 7pm on Friday and 1am on Saturday morning to contact Crime Stoppers on 1800 333 000 or online at (www.crimestopperssa.com.au).
