A WOMAN who allegedly held a teenager captive and bound for three days also tortured her and broke her bones, a court has heard.

Police allegedly discovered a 19-year-old woman tied up and significantly injured in a Clearview St home in Waterford West around 10.55pm on Wednesday, after they had been called there to investigate an unrelated matter. Two children were at the house when police entered, officers say.

It is alleged the woman had been taken to the house and held captive since Monday morning by a 40-year-old woman who lived at the home.

Christine Louise Thomson appeared in the Beenleigh Magistrates Court this morning.

She applied for bail but was denied.

The court heard Thomson allegedly tortured the young woman because she believed she had taken her car.

“It is a horrendous assault,” police prosecutor Sergeant Wendy Moman said.

“Our gravest of concern is the welfare of the victim.”

Thomson is charged with kidnap, deprivation of liberty, torture, stealing and dangerous drug possession.

The court also heard Thomson had previously been charged with burglary, assault and harming animals. The magistrate said Thomson’s history was “of concern”.

The matter was adjourned to January 17.

Earlier on Thursday, Detective Inspector Tod Reid said the teenage victim had suffered severe injuries to her torso and face including burns, abrasions, bruising and lacerations.

“At this stage we came here in relation to another inquiry, and at that time we happened to find the (teenager) inside the residence at that time,” he said.

“There is some information that she was given really basic necessities by her (alleged) captor, so yes some food and water was provided.”

He said part of the investigation was to determine if other people were involved.

“Two people that were present were kids, and we’ve got their welfare in mind in terms of whether they were exposed to any of this (alleged) offending and to make sure that their welfare is paramount and that they’ve been relocated,” he said.

Police said the women were known to each other.

Investigations are continuing.
