Joseph Magezi, a businessman and proprietor of CTM Tiles hardware in Nsambya, was yesterday found dead in his flat in Bugolobi.
Police had to break into his flat on Block 21 after neighbours complained of a foul smell which had been wafting in the air for days.
Magezi, according to one of the neighbours, was last seen on Saturday evening.
Police is investigating whether he committed suicide since he was living alone in the flat.
Magezi is the son of Joan Magezi, a former principal private secretary to President Museveni.
CTM is one of the leading suppliers of bathroom ware and tile products.
Kampala Metropolitan deputy spokesperson, Luke Owoyesigyire, said investigations are on-going.
