SEOUL (AFP) - The head of a top South Korean food and entertainment conglomerate, CJ Group, presented himself to prosecutors on Tuesday to face questioning over alleged tax evasion and embezzlement.

Chairman Lee Jae Hyun, the 10th richest man in the country, showed up at the Seoul Central District Prosecutors' Office in response to a summons sent last week.

"I am sorry to cause concern among the people. I will sincerely respond to questions (from the prosecution)," the 53-year-old tycoon told journalists before he entered the Prosecutor's Office.

Prosecution authorities searched the group's headquarters last month.

Mr Lee allegedly dodged 51 billion won (S$55.6 million) in taxes and diverted another 60 billion won in company funds.
