SEOUL, May 4 (Xinhua) -- South Korean police on Friday sought a warrant to arrest the daughter of Korean Air Lines' chairman over allegedly assaulting and insulting an advertising company executive at a business meeting in March, according to local media.

The Seoul Gangseo Police Station was quoted as saying that it requested a warrant to detain Cho Hyun-min, a daughter of Korean Air Lines Chairman Cho Yang-ho, on charges of assault and obstruction of business.

The younger Cho, who oversaw marketing at the airline, was suspected of yelling at an advertising executive during a business meeting in March as he failed to answer her questions properly.

She was even charged with hurling a glass cup at him and throwing a paper cup of beverage at other participants.

Accusations included her abusive language and assault that obstructed business by stopping the business meeting.

She denied the allegations, saying she hurled the glass cup at where nobody stands and just pushed the paper cup to the side, not throwing beverage at people. She also claimed she had the right to stop the business meeting.

The police grilled her Tuesday over the allegations, after raiding the offices of the Korean Air Lines last month. It said she may try to destroy evidence, referring to the need for her detention.

The founding family of the Korean Air Lines has been recently under criticism from the public for the abuse of underlings and subcontractors.

She is a younger sister of Cho Hyun-ah, a former Korean Air Lines vice president who was jailed for violating airline safety laws.

In 2014, Cho Hyun-ah yelled and used abusive language at flight attendants because she was served macadamia nuts in an unopened package, not on a plate. She even ordered the plane back to its gate while it was taxiing at New York's Kennedy International Airport.

Cho was sentenced to one year in prison, but she was released by an appeals court later.
