[THE INVESTOR] The chief of a major Korean drug maker was summoned by police on Aug. 2 to face questioning over allegations of verbal harassment of his chauffeurs.

Rhee Jang-han, chairman of ChongKunDang Pharmaceutical, appeared at the special crime unit of the Seoul Metropolitan Police Agency at around 10 a.m., according to the Seoul police. 

Rhee, 65, is suspected of hurling invectives at four of his private car drivers and forcing them to violate traffic regulations. They have all quit their jobs.

The chairman is also accused of offering his business partners erectile dysfunction pills as gifts without obtaining prescriptions.

“I do ask for forgiveness from the public and those who were hurt by what I did,” he told reporters. “I will answer in detail (to the police).”

The allegations came to light as recorded conversations between him and one of the drivers were released via online and the media.
