However, Tourism minister Dan Mwazo, who met Baron Nicholas John Monson on Monday, called for patience as the police probe cause of the death.

Mwazo had visited Monson at the Swahili Beach Hotel where he is residing to console and assure him that the government will arrest and prosecute those responsible for his son's death.

"I am I to interpret your expression of sorrow that the official line that my son died of a drug overdose has been completely gotten rid of and that you accept that he died of a brain hemorrhage?" posed Monson.

Monson, however, accused the government of treating the matter lightly. He said the slow pace of investigations has given those responsible for his son's death to cover up their tracks by tampering with evidence.

"This does not give confidence to people who wish to come out to Kenya because they are scared now. Have you seen the press reports around the world?" Monson posed.

But Mwazo said the incident should not cast Kenya as an unsafe place for tourists. He said the police reforms in Kenya will ensure that such incidences are never witnessed in the country.

Monson claimed that Alexander, who was cremated on Monday, was beaten, kicked in the testicles, and left unconscious for 45 minutes behind the police counter.

"We had family friends who had to plead with the police to take him to hospital. When they took him to hospital, they still insisted that this unconscious man be handcuffed to the bed," he said. He vowed to follow up the matter until justice is done.
