Dawood Safi, 23, fatally stabbed 49-year-old Wayne Broadhurst on 27 October 2025. Earlier that day he had attacked his 45-year-old landlord, Shahzad Farrukh, and a teenage boy in Midhurst Gardens, Uxbridge.

Jonathan Laidlaw KC told the court four mental health experts had concluded Safi suffered a "complete mental collapse" during the incident.

Psychiatrists described him as neurotic, with a tendency to ruminate and worry, and said he had developed a "rigid sense of right and wrong".

Laidlaw said: "He was in a psychotic state and had lost contact with reality. He was not able to distinguish what was real and what was not. He was hearing voices and had delusional beliefs."
