A Metropolitan Police officer will face a misconduct hearing after being convicted of multiple serious sexual offences. PC Dion Arnold, 33, was found guilty of eight offences, including four counts of rape, two counts of assault by penetration, and two counts of sexual assault.
The conviction was delivered on Thursday, April 16, following a trial at Guildford Crown Court, which was conducted after an investigation by Surrey Police. Arnold remains suspended from duty and is scheduled to be sentenced on Wednesday, June 22.
Chief Superintendent Dan Knowles, head of policing in London’s South West, praised the courage of the victims. He 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 was crucial in securing this conviction and stopping Arnold from ever harming another woman in this deplorable way.”
He added, “We are sickened he used his position to gain trust and commit these horrendous crimes while serving as a Met officer. We understand the impact this has on public confidence, but we urge anyone with information to come forward. Our professional standards teams have been significantly strengthened to root out wrongdoing.”
Arnold began his police career as a Special Constable in 2014 and became a full officer in 2016 with the South West Command Unit. He was arrested in March 2025 after Surrey Police received multiple reports of rape and sexual assault occurring between June 2023 and March 2025.
Forensic analysis of phone evidence revealed Arnold admitted to “going too far” but continued offending despite the victims’ refusals. Four women came forward, resulting in a total of 17 charges.
The Metropolitan Police have been intensifying efforts to address misconduct within the force. Since 2022, approximately 1,500 officers and staff have left due to misconduct allegations, with internal reports of wrongdoing nearly tripling as a result of an improved reporting culture.
Operation Onyx, a Met initiative, reviewed over 1,600 sexual and domestic abuse cases, leading to 378 dismissals aimed at protecting the public. Chief Superintendent Knowles emphasised, “The overwhelming majority of our workforce refuse to tolerate poor behaviour. We are committed to rooting out those who betray public trust.”
