A serving Metropolitan Police officer has been convicted of assaulting a vulnerable man experiencing a mental health crisis, following a trial at Snaresbrook Crown Court.

PC Rhys Walmer, attached to the East Area Basic Command Unit, was found guilty on Thursday, 15 May of assault by beating and administering a noxious substance with intent to injure/aggrieve/annoy, after using disproportionate force on a man already restrained in hospital.

Walmer, who had been on restricted duties since November 2022, will be sentenced on 14 July. He is also due to face a misconduct hearing now that criminal proceedings have concluded.

 Hospital Assault Incident

The court heard the assault took place on 3 August 2022 at an East London hospital, where officers were guarding a man who had been arrested and detained under the Mental Health Act.

The man was already in handcuffs, limb restraints, and wearing a spit guard, awaiting a psychiatric assessment.

Despite the man being physically restrained by three officers, PC Walmer sprayed PAVA directly into his face as he attempted to stand. He then proceeded to strike the man 14 times with a baton—all while the victim remained fully restrained.

Staff Sound the Alarm

Concerned by the level of force used, hospital staff reported the incident to a police supervisor. An internal investigation was launched by the Policing Standards Unit and the case was escalated to the Met’s Directorate of Professional Standards.

Walmer was formally charged by postal requisition in June 2024, following a detailed inquiry.

Senior Police Response

Chief Superintendent Stuart Bell, head of the East Area BCU, condemned Walmer’s actions:

“The level of force used by PC Walmer was not proportionate or necessary and his actions have been subject to proper scrutiny and accountability through the legal process.

I would like to thank the hospital staff for quite rightly raising their concerns with the officer’s supervisor.”

He added that excessive use of force will not be tolerated, and officers who fail to uphold professional standards will be brought to justice.

 Misconduct Hearing Pending

With a criminal conviction now secured, Walmer will be the subject of a Met Police misconduct hearing to determine his future in the force. He remains on restricted duties pending that outcome.
