Man pleads guilty to manslaughter through diminished responsibility

A 32-year-old man has pleaded guilty to manslaughter through diminished responsibility, after he stabbed his stepfather in his own home.

Adejuwon Olufemi Alexander Jnr Oyekan, 32 (08.11.1992) of Melina Close, Hayes, pleaded guilty to manslaughter through diminished responsibility at the Old Bailey on Monday, 24 February 2025.

Officers were called to a residence in Hayes in the early hours of Tuesday, 11 July 2023, to reports Oyekan had stabbed his 54-year-old stepfather Jason Thompson.

When they arrived, officers were faced with Oyekan still armed with the knife which he had used to attack Jason.

After the first responding officers had gained entry to residence they challenged Oyekan, initially using their tasers in an attempt to disarm him. When this was unsuccessful, they then left the address to await support from armed response officers to detain him.

When officers returned to the property, they made it their priority to assist Jason. However, sadly and despite the best efforts of the emergency services, Jason died from his injuries at the scene.

Detective Chief Inspector Laura Semple from the Met’s Public Protection Partnership, said: “Our thoughts remain with Jason’s family throughout this difficult time.

“I’d like to thank the first responding officers who attend the scene and demonstrated huge bravery to challenge the suspect, who was armed and acting aggressively.

“Their quick thinking, to use the tools at their disposal, guaranteed Oyekan was admitted to custody from the scene, and did not go on to pose a wider threat to the public.”

Oyekan was arrested at the scene and charged with murder on Wednesday, 11 July 2023.

He is due to be sentenced Thursday, 10 April.
