Tom Cholmondeley, son of the fifth Lord Delamere, is dead.
He died on Wednesday while receiving treatment at MP Shah Hospital.
MP Shah Hospital chief executive officer Anup Das said Mr Cholmondeley, 48, died of cardiac arrest on Wednesday afternoon at 2.15pm as he recovered from hip replacement surgery at the facility.
Mr Das said: “He was admitted on Tuesday as a private patient — that is admitted by visiting doctors — in our facility and he underwent the surgery. He was recovering at the Intensive Care Unit when he developed cardiac arrest and died.”
In April 2005, Cholmondeley shot and killed a KWS game ranger at his expansive Soysambo ranch near lake Naivasha.
He claimed self-defence, and the murder case was dropped before going to trial.
The man shot and killed a poacher In May 2006. He was acquitted of murder, but found guilty of manslaughter and sentenced to eight months in prison. He was released on October, 2009.
