Samsung Group denies any wrongdoing
The boss of South Korea's Samsung Group has appeared before special prosecutors to be questioned over allegations of corruption at the firm.
Lee Kun-hee, chairman of the company, the country's largest conglomerate, is being questioned in regard to an investigation that started in January.
Samsung is accused of operating a 200bn won ($215m; £108m) slush fund to bribe prosecutors, judges and civil servants.
The company and Mr Lee continue to deny the accusations.
The investigations started after the allegations were made by former Samsung lawyer Kim Yong-Chul.
Prosecutors are due to end the investigations on 23 April, with the conclusions expected before the end of the month.
Best-known for its electronics unit, Samsung is also one of the world's largest shipbuilders.
It also has businesses in the financial, chemical and entertainment industries.
With a global workforce of 754,000, it enjoys annual profits of more than $14bn.
