A former Metropolitan police officer named Mark Tyrrell has been found guilty of multiple offenses, including rape and sexual assault, following a trial at Southwark crown court, according to The Guardian. The 57-year-old former officer previously served in the parliamentary and diplomatic protection command, the same unit where convicted criminals Wayne Couzens and David Carrick had worked.

During the trial, the court heard that Tyrrell committed the offenses against a woman he met through his work as an officer. Prosecutor Catherine Farrelly KC stated that when the victim resisted his sexual advances, Tyrrell chose to take what he wanted. Following the assault, he reportedly acknowledged his actions to the victim, stating phrases such as “I don’t believe what’s just happened” and “do you realise that what I’ve just done, that was rape?”
Trial Verdict and Charges Against Mark Tyrrell
Jurors convicted Tyrrell of one count of rape, three counts of sexual assault, and one count of perverting the course of justice. However, jurors found him not guilty on 13 other charges, which included an additional count of rape. In his defense testimony, Tyrrell claimed that sexual intercourse between them was always consensual and maintained that force was never used.
Concerns regarding his conduct came to light after officers attended the victim’s address for a separate matter and discovered Tyrrell hiding beside her bed. Investigators found that he attempted to delete messages exchanged with the woman. In one recovered message, he apologized for “being a sex offender” and for “ruining your life by being in it.”
Prior Admissions and Leadership Response
Before the conclusion of the trial, Tyrrell had already admitted to misconduct in a public office. He additionally pleaded guilty to perverting the course of justice by previously persuading the victim to lie to police regarding why he was present in her bedroom.
Chief Superintendent Sara Leach, a commander within specialist operations, condemned the actions of the former officer. She remarked that such behavior is abhorrent, particularly when perpetrated by someone trusted to serve within the organization. Tyrrell, a resident of Meltham in West Yorkshire, is scheduled to be sentenced on December 16.
The case has drawn renewed public attention due to Tyrrell’s former unit, which previously employed Wayne Couzens—who kidnapped, raped, and murdered 33-year-old Sarah Everard in 2021—and David Carrick, who is serving multiple life sentences for attacks against more than a dozen women.
