John Harun Mwau’s Remarkable Journey from KACA Boss to Billionaire Businessman
John Harun Mwau is a Kenyan billionaire businessman, former Kilome MP, and founding director of the Kenya Anti-Corruption Authority (KACA). He headed KACA in the late 1990s before his tenure ended following a tribunal investigation, then moved into politics and business, including interests linked to Nakumatt Supermarkets.
His name later became associated with Kenya’s drug-trafficking controversy. Then Internal Security Minister George Saitoti publicly mentioned Mwau among several prominent Kenyans alleged to be linked to the drug trade, including William Kabogo and other figures.
In June 2011, the United States under President Barack Obama designated Mwau under the Foreign Narcotics Kingpin Designation Act, accusing him of involvement in international narcotics trafficking and imposing financial sanctions.
Mwau strongly denied the allegations and challenged the designation through legal avenues, maintaining that he was innocent.
This is the case of businessman cum politician, John Harun Mwau, who once served as a police officer in his 20s. While in the police force, Mwau participated in the Olympic Games as a rifle shooter in 1968 and as a pistol shooter in 1972.
So talented was Mwau in the sport that he was christened, “the Boss”. It is reported that he enjoyed using a sharpshooter rifle while on duty due to his preference for long-range shooting competitions.
Three years ago, Atul Shah, the CEO of the retailer, said in an interview that the company had a valuation of $400 million. That valuation is highly unlikely today considering that Nakumatt’s profit before tax for 2015 was less than $3 million, compared to more than $10 million in 2013.
