Two daughters of Korean Air chairman Cho Yang-ho are stepping down from their positions at the company amid allegations of abusing power.
One of the daughters, Cho Hyun-min, also known as Emily and a senior vice president at the airline, is under investigation by police for possible assault after she allegedly sprayed water at a colleague during a business meeting.
She denied throwing water but admitted to shoving an advertising agency manager.
Her older sister, Heather Cho, made global headlines over a notorious “nut rage” incident in 2014, when she lost her temper over the way she was served macadamia nuts in first class and ordered a Koran Air flight to return to its airport gate in New York.
aShe served five months in jail after being convicted of violating aviation safety, coercion and abuse of power in 2015 but returned to work as an executive of Korean Air’s hotel affiliate in March.
The airline’s chairman said in a statement that he apologised to South Korean people and his employees.
The sisters are granddaughters of the founder of Hanjin Group, one of South Korea’s major family-run business empires.
Their brother, Cho Won-tae, remains president and chief operating officer of Korean Air.
The BBC reported local news agency Yonhap as saying Korean Air offices and homes of the three offspring were searched by police on Thursday amid separate allegations they had avoided paying duties on luxury goods.
