A Lincolnshire aristocrat has demanded that Kenyan officials launch a murder investigation after police officers, linked with the death of his son, were cleared.
Alexander Monson, 28, heir to an estate covering 1,200 acres across South Carlton, died in May after spending nine hours in a Kenyan police cell.
He was arrested for smoking cannabis outside a bar near his mother's home in the coastal resort of Diani, south of Mombasa. Officials claimed that his death was the result of complications from taking drugs.
But an independent pathologist hired by the Monson family found that Alexander had suffered a severe blow to the head and had bruising on his arms and groin as if he had been trying to defend himself.
The investigation was conducted by director of criminal investigations Mohamed Amin.
And while it confirmed that Alexander died from severe head trauma, it has failed to determine who or what was responsible for the fatal injury.
Nicholas Monson, the 12th Lord Monson of Burton and the 16th Baronet of Carlton, upholds his claim that his son was the victim of police brutality.
He said: "We have said from the very beginning that Alexander was brutally killed in police custody which is made perfectly clear by two autopsy reports.
"And we strongly disagree with Mr Amin's final statement that, in his opinion, 'the circumstances surrounding the death of Alexander can be best determined by a public inquest'.
"What must be conducted instead is a murder inquiry which must be opened immediately and the suspects who were responsible for Alexander at the time of his incarceration be arrested, charged and tried in a court of law.
"We do, however, concede that there is at least one good point in the investigation.
"Government analysts were unable to find any drugs in his body so at least he has gotten rid of that unpleasant smear.
"This investigation is a setback, but the war isn't lost. When you rule out all other possibilities, you are left with a group of people responsible who all happen to be wearing police uniforms.
"People tell me that I will never have justice in Africa, but I'm not ruling it out.
"There are some very good progressive forces in Kenya and there are people and new bodies being appointed with powers over the police who are having a very close look at this."
Alexander's ashes will be laid to rest at his Lincolnshire home at a family service in August.
Lord Monson will also be holding a memorial to his son at St Mary Abbots Church, in Kensington, on September 19.
He also hopes to launch the Alexander Monson Foundation at the memorial, which will work to protect both tourists and civilians from police brutality in Kenya.
