Education Secretary Amina Mohamed on Sunday morning lost her younger brother Yusuf Jibril after a short illness.
A statement from the ministry said Jibril was rushed to Meridian Hospital in Nairobi West, after complaining that he was unwell.
He died while undergoing treatment.
Mr Jibril was the Chairman of Paddock Investments and had been at logger heads with the residents of Runda Estate where his company wanted to build a four-star hotel.
In March, environment management agency Nema invited residents to submit their views over the planned Sh1 billion four-star hotel and luxury suites.
Residents had opposed the amalgamation of 15 residential plots leading to a change of user for construction of a hotel, saying it would disrupt their serene, safe and secure noise-free environment.
“The amalgamation and change of user is against zoning restrictions and is in breach of other special conditions regulating the parent grant of Runda Estate,” Runda Residents Association chairman Isaac Gitogo said in a letter to the Nairobi county government.
Jibril’s family members, including the Cabinet Secretary, are currently making funeral arrangements following the demise.
