The second daughter of the chairman of Korean Air Lines Co. returned home from an overseas trip on Sunday amid controversy over claims that she hurled water into the face of an advertising firm employee last month.
Police launched a preliminary inquiry into Cho Hyun-min, a senior executive at the country's largest air carrier, on Friday after media reports that she yelled and threw a water bottle at a manager of the company's advertising agency during a business meeting in her office in Seoul on March 16.
Cho is the sister of Cho Hyun-ah, who was jailed in 2014 in the so-called nut rage scandal, in which she ordered her flight back to an airport gate in New York because she was upset about the way her nuts were served on the plane.
