Seoul, South Korea ? A South Korean business tycoon was arrested Friday for allegedly taking part in a revenge attack on bar workers after his son was hurt in a fight at a karaoke pub.

Hanwha Group Chairman and CEO Kim Seung-youn is suspected of kicking, punching and using a steel pipe to attack bar workers allegedly involved in a scuffle with his 22-year-old son on March 8 at a karaoke pub.

After questioning Kim at a hearing earlier Friday, the Seoul District Court accepted a prosecution request made a day earlier to issue an arrest warrant for him, said Hanwha spokesman Ju Cheol-beom.

Judge Lee Kwang-man said the warrant was issued on “concerns that he may try to destroy evidence,” according to Yonhap news agency.

“I feel calm,” Kim said as police officers took him from the prosecutors’ office where he had been waiting all day.

Kim was put in a police van and taken to be held in custody at the Namdaemun Police Station in central Seoul.

In a statement released through his company, Kim said he would “humbly accept the law’s judgment.”

“I plan to explain everything that I know, truthfully and sincerely,” the statement said. “I am very pained and ashamed for not having been honest for the past two months.”

Earlier Friday, Kim said he regretted that he “failed to control impulsive emotion” and apologized for causing trouble.

“I hope there will never be a silly father like me again,” Kim said after the court hearing.

The details of the case, which media have likened to a gangster movie, have drawn intense interest in South Korea, where the heads of family-controlled conglomerates wield economic, political and social clout.
