SEOUL ¨C South Korean police are seeking an arrest warrant for the youngest daughter of Korean Air Lines¡¯ chairman on suspicion of assault during a recent angry outburst, police said on Friday.

Cho Hyun-min, the younger sister of the notorious ¡°nut rage¡± heiress of the airline, who got into trouble over a petulant outburst in 2014, is being investigated over accusations that she threw a drink at people at a business meeting last month.

Cho, 34, made a tearful apology during a media scrum on Monday when she made her first appearance for questioning at Seoul¡¯s Gangseo police station, which is leading the investigation.

¡°The Seoul Gangseo police station requested an arrest warrant for a former senior vice president, Cho Hyun-min, related to the case of assault and obstruction of business,¡± the police said in a statement.

Cho denied any wrongdoing during questioning, police said.

Police said prosecutors would decide whether to send the request to court for a ruling on her arrest.

Investigators fear evidence in the case may have been destroyed, police added in the statement.

¡°As a result of digital forensics, there is a risk of destroyed evidence, given circumstances where Korean Air discussed measures to save the situation,¡± they said.

Korean Air declined to comment on Friday.

The younger Cho stepped down from her position at the airline after her father, Cho Yang-ho, its chairman, apologized for the behavior of his daughters.

The younger sister¡¯s tantrum has reignited public impatience with family-run conglomerates known as chaebol that dominate South Korea¡¯s economy, over what some people see as unchecked bad behavior by the rich and powerful.

¡°Police will thoroughly investigate and take stern action against gapjil,¡± the police statement said, using a Korean term for high-handness by those in positions of power.
