A serving Metropolitan Police officer has been found guilty of a series of rapes and sexual assaults.
Dion Arnold, 33, worked in a domestic abuse unit and was exposed following a trial at Guildford Crown Court, where he was convicted of four counts of rape, two counts of assault by penetration, and two counts of sexual assault.
The crimes did not involve victims he met through his role as a police officer.
One woman came forward and reported Arnold to police in March 2025, leading to his arrest.
A subsequent investigation led officers to find a list of women’s names on his phone.
Metropolitan Police Chief Superintendent Dan Knowles said: "We are sickened that Pc Arnold carried out these horrendous crimes while serving as a police officer in the Met, something he deliberately told the victim-survivors from the outset so that they would have more trust in him.
"We do not underestimate the impact that cases like this have on the confidence that women and girls have in our organisation but would encourage anyone in a similar situation to report allegations."
When police contacted individuals from the list, three women who had not known each other made separate allegations of rape or sexual assault.
During the trial, the women described feeling pressured by Arnold and said they were ignored when they repeatedly told him to stop.
Claire Gallagher, senior crown prosecutor at the Crown Prosecution Service, said: "These women believed that, as a police officer, they could trust Arnold and would be safe with him.
"He abused that trust in the most appalling way."
Ms Gallagher said Arnold’s knowledge of consent was clear because of his professional role and was even referenced in messages between them.

She said: "One told him in messages that he had ‘destroyed and broken her’, while another described feeling ‘powerless’ and that she had no option but to submit.
"In law, that is not consent.
"Arnold deliberately targeted women that he thought would not stop him and would never have the courage to report him.
"They have proved him wrong and have seen him brought to justice for his appalling crimes."
Arnold, an Army reserves medic, met some of his victims through online dating apps.
He will be sentenced at Guildford Crown Court on June 22.
The Metropolitan Police have confirmed that he remains suspended from duty and will face a misconduct hearing following his conviction.
