Italy chocolate tycoon Pietro Ferrero dies in S Africa
Mr Ferrero, 48, was on a business trip and died after falling off his bicycle, probably because of an ailment, the company said.
He was joint chief executive - along with his brother - of the Ferrero group, which owns Nutella and Kinder.
His father Michele, Italy's richest man, turned the company into a global giant of the confectionery industry.
Nutella
Mr Ferrero's grandfather, also Pietro, started the company in 1942 in the northern Italian town of Alba, where the firm is still based.
Because of wartime shortages, chocolate was difficult to obtain. The elder Pietro Ferrero hit upon a recipe which combined cocoa with locally abundant hazelnuts.
That concoction - Nutella spread - became an international success.
In 2009, the company expressed interest in a bid for the UK confectionery group, Cadbury. However, it abandoned the plan and Cadbury was instead taken over by US-based Kraft Foods.
The Ferrero company had an annual turnover of 6.6 billion euros ($9.4 billion) in its 2009-2010 financial year, the AFP news agency reports. Kazinform cites BBC. See www.bbc.co.uk for full version
