A Kenya hospital official says a descendant of British aristocrats who twice had been accused of murdering locals has died after cardiac arrest.

The chief executive of MP Shah hospital, Anup Das, on Wednesday announced the death of Lord Delamere's heir Thomas Cholmondeley.

The 48-year-old had been accused of killing two Kenyans in separate incidents that stirred fierce resentment over race and land.

Cholmondeley claimed self-defense and was cleared without trial in the killing of an undercover wildlife ranger who was arresting Cholmondeley's workers suspected of poaching.

He was then convicted of manslaughter in the 2006 shooting of a black poacher. The judge reduced the charge from murder, saying that Cholmondeley's attempts to give first aid proved that he accidentally shot the poacher when aiming at his dogs.
