A court has heard a WA Police officer on trial for allegedly assaulting and unlawfully detaining a woman in suburban Perth was told by his partner he was "out of line" during the incident.
It is alleged First Class Constable Alister Swift dragged a woman through her Cloverdale house while she was handcuffed in January 2020.
The then 29-year-old is also alleged to have kicked her when he was trying to force her into a police vehicle.
Prosecutor Peter Phillips told the District Court the alleged victim "wasn't mentally well" and had tried to take her own life on January 21, 2020.
Her partner had called an ambulance and she was taken to hospital for assessment before being released.
Police had also attended and taken the woman into custody, using handcuffs.
The next day, the woman was arguing with her partner about needing to collect belongings from her daughter's unit.
The court heard that her partner, fearing another attempt at self-harm, called an ambulance.
Because the complainant was agitated, police attendance was requested, Mr Phillips told the court.
Constables Alister Swift and Cassandra Chapman attended, and the woman's partner explained the issue with the belongings at the unit, and told them he wanted her to "stop yelling at him".
The court heard there was a discussion about whether the man wanted a police order, issued under the Restraining Orders Act, to protect him from potential violence.
Handcuffs applied twice
But when police tried to run a search on the woman's name, they made a spelling mistake.
The prosecutor said Constable Swift asked the woman for her name and she responded that his colleague already had it, asking, "what are you, stupid?"
He told the court Constable Swift decided to make an arrest, pushing the woman into a bedroom and applying handcuffs.
Mr Phillips said the woman banged her head on the wooden end of bed and asked to be able to get items from the unit.
Constable Chapman removed the cuffs and helped her wash her wrists and face.
Mr Phillips told the court the woman had red marks on her wrists and said "she'd been treated roughly" the day before.
The court heard that Constable Swift still wanted details for the police order, but the woman had said she "didn't care" as she would "probably breach it anyway".
Mr Phillips said Constable Swift took the woman "to ground" and applied handcuffs again.
'You're out of line'
Mr Phillips said Constable Chapman then asked Constable Swift, "what are you doing?"
The court was told the woman was dragged by Constable Swift over the bed, over a wooden box and onto the floor.
Mr Phillips told the court she was dragged "for approximately five metres", to the front door of the house.
He said Constable Swift pushed the woman against her partner's car, and Constable Chapman had told him, "you're out of line".
The court heard the woman had referred to Constable Swift as a "bully" and called him other names.
Dispute between officers
At the police vehicle, Mr Phillips said Constable Swift kicked the woman's feet to get her into the vehicle.
The court heard that when Constable Chapman tried to prevent the kicking, Constable Swift told her to "do as I say, I am your superior."
The court was told the woman was taken to a police station, and the police order was completed before she was transported to Royal Perth Hospital.
She was discharged soon afterwards and was told she was no longer under arrest.
The prosecutor said there was "bruising and swelling to her right wrist and hand" and bruises on her ribs, forearms and legs.
Mr Phillips told the court the woman had been detained from the point the handcuffs were on.
It was the state's case that Constable Swift did not have grounds to reasonably suspect she was committing an offence, and the force used was "disproportionate".
Defence lawyer Anthony Eyers said his client had "acted lawfully".
He told the court there was a question as to whether Constable Swift caused "any bodily harm at all", or whether injuries may have been caused on the preceding day.
Mr Eyers said the woman was "angry and confrontational" when officers arrived, and his client "acted sensibly, reasonably, exercising good judgement" in the circumstances.
He called on the jury to consider Constable Chapman and "her actions, her indecision" in providing "little or no support for her police partner".
Woman 'begged' not to be handcuffed
The woman at the centre of the allegations gave evidence via videolink from a separate room in the District Court building.
She told the court that Constable Swift had told her he was going to breach her on an order, but she did not know how this could happen because there was no order.
She said he was "adamant" he had to cuff her hands behind her back, she told the court, despite her request for the front.
"I just went into absolute f***ing shock," she said.
"I begged him and begged him not to cuff me from behind."
The female officer then uncuffed her, she said, before Constable Swift tried to cuff her again.
The woman said only one wrist was cuffed, and Constable Swift "spun me and threw me onto the bed".
"I was not with it at this point," she said. "I couldn't even breathe, I just wanted to get out."
At one point, she said, the female officer "stood between the two of us".
When they were at the police vehicle, she said Constable Swift had been trying to tighten the handcuffs, and "kicked my feet out".
She said she was not wearing any shoes.
The woman told the court that after she arrived at the "police lock-up", she was strip searched, but could not give fingerprints as her hand was too swollen.
She was told by police she was not under arrest but was handed an order saying she could not go home.
The court was shown several photos the woman said she had taken, of bruises on parts of her body.
