Met officer found guilty of series of rapes and sexual assaults
Dion Arnold will be sentenced on June 22
A Metropolitan Police officer who worked on domestic abuse cases has been found guilty of a series of rapes and sexual assaults, the Crown Prosecution Service (CPS) said.
Dion Arnold, 33, was found guilty of four charges of rape, two charges of assault by penetration and two charges of sexual assault after a trial at Guildford Crown Court, the CPS said.
Arnold worked in a unit dealing with domestic abuse and was an Army reserves medic when met some of the women he assaulted through online dating apps, prosecutors said.
One woman reported Arnold to the police in March 2025, leading to his arrest.
List of names found
An examination of his phone revealed a list of women’s names and when contacted, three unrelated women came forward with allegations of rape or sexual assault, the CPS said.
The CPS said that during the trial, women gave evidence that they felt pressured by Arnold and had to submit to him and that, when they repeatedly asked him to stop, he ignored them.
Claire Gallagher, Senior Crown Prosecutor from 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.
“As a police officer working with victims of domestic abuse, Arnold knew exactly what the law of consent means. These women asked Arnold to stop and he knew that, even referring to it in messages between them.
“The impact that Arnold had on these women cannot be underestimated. 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.”
'Sickened'
Chief Superintendent Dan Knowles, who leads policing in the South West where PC Arnold worked, said: “The victim-survivors in this case have shown enormous courage by coming forward and reporting PC Arnold's crimes to police, as well as giving evidence in court.
“Their testimony has played a crucial part in his conviction and in ensuring that he won’t be able to treat any other woman in this deplorable way.
“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.
“As part of our unprecedented drive to improve standards, we have grown our professional standards teams over the last three years to ensure we are robust in investigating matters at the earliest opportunity. We have invested in more officers who are specifically and proactively focused on uncovering and dealing with wrongdoing, including our specialist Public Protection team."
Arnold will be sentenced on June 22 at Guildford Crown Court.
