The Korea Customs Service on Monday applied for an arrest warrant for Korean Air chief Cho Yang-ho's troubled daughter Hyun-ah on charges of using airline staff to smuggle luxury goods for her personal use.
Cho Hyun-ah was internationally disgraced in the 2014 "nut rage" scandal that saw her abuse crew because she had been served nuts in a bag instead of a bowl aboard a flight.
The KCS started investigating after a tipoff from Korean Air staff, conducting four separate raids on the home and offices of the Cho family that netted piles of handbags and accessories and questioning Cho Hyun-ah three times.
Cho denied most of the charges, but customs officials say they have enough evidence after tracking the sources of the luxury goods seized in the raids.
The entire family have been the target of recent investigations. Her sister Hyun-min has been indicted on charges of assault for throwing a bottle of water at an advertising staffer during a meeting. Her father faces trial for embezzlement and tax evasion. And her mother, Lee Myung-hee, faces charges of assaulting staff. Her brother has been stripped of his university degree, which he obtained by cheating.
The courts have so far refused arrest warrants for all of them.
