Former Met Officer Mark Tyrrell Convicted of Rape and Sexual Assault 2026

Mark Tyrrell, a former Metropolitan Police officer who served in the same unit as convicted killers Wayne Couzens and David Carrick, has been found guilty of rape and sexual assault. The 57-year-old was convicted at Southwark Crown Court of one count of rape, three counts of sexual assault, and one count of perverting the course of justice.

The case has reignited concerns about the culture within the Met's parliamentary and diplomatic protection command, where both Couzens and Carrick also worked. Tyrrell's conviction follows a trial that heard disturbing details of his behavior toward a woman he met through his work as an officer.

Who is Mark Tyrrell and what was he convicted of?

Mark Tyrrell is a former police constable who was attached to the parliamentary and diplomatic protection command. This is the same unit that employed Wayne Couzens, who kidnapped and murdered Sarah Everard in 2021, and David Carrick, who was convicted of dozens of rapes and sexual assaults.

Tyrrell was found guilty of raping a woman by having sex with her after she repeatedly said no. The court heard that after the attack, he told her: "I don't believe what's just happened" and "do you realise that what I've just done, that was rape?" He was also convicted of three sexual assaults and of perverting the course of justice by attempting to delete messages with the woman.

He was found not guilty on 13 other charges. The prosecution, led by Catherine Farrelly KC, alleged that when the woman resisted Tyrrell's advances, "he simply chose to take what he wanted."

Why does this case matter for the Met Police?

The conviction of yet another officer from the same unit as Couzens and Carrick raises serious questions about the Met's vetting and disciplinary processes. The parliamentary and diplomatic protection command has now produced three high-profile sex offenders, suggesting a systemic issue rather than isolated incidents.

This pattern undermines public trust in the police, particularly among women who may already be hesitant to report sexual violence. The fact that Tyrrell met his victim through his work as an officer adds another layer of betrayal, as he exploited his position to gain access to her.

The case also highlights the importance of victims coming forward. The woman in this case cannot be identified for legal reasons, but her courage in reporting the crime led to Tyrrell's conviction and removal from the force.

What are the key details of the case?

The court heard that concerns were raised when officers attended the woman's address for a separate matter and found Tyrrell hiding by the side of her bed. This discovery prompted an investigation into his behavior.

During the investigation, it emerged that Tyrrell had attempted to delete messages with the woman. In one message, he said he was "sorry" for "being a sex offender" and "for ruining your life by being in it." This admission was used as evidence against him.

The trial at Southwark Crown Court concluded with guilty verdicts on five counts. Tyrrell now faces sentencing, which will be determined at a later date.

How does this compare to other Met scandals?

The Met Police has been rocked by a series of scandals in recent years, most notably the cases of Wayne Couzens and David Carrick. Couzens was sentenced to a whole-life term for the kidnap, rape, and murder of Sarah Everard. Carrick was given a minimum of 30 years for 85 serious offenses, including 48 rapes.

Both men served in the same unit as Tyrrell, leading to accusations that the Met has a culture of misogyny and inadequate vetting. The force has pledged to reform, but this latest conviction suggests that more work is needed.

What should victims of sexual violence do?

If you or someone you know has been affected by sexual violence, it's important to know that support is available. Organizations like Rape Crisis and Victim Support offer confidential advice and can help you navigate the reporting process.

Reporting to the police can be daunting, especially when the perpetrator is an authority figure. However, the conviction of Mark Tyrrell demonstrates that justice can be served, even when the odds seem stacked against the victim.
