South Korean prosecutors are seeking to arrest the former executive at Korean Air Lines Co. who forced a flight to return over a bag of macadamia nuts and a current executive for attempts to cover up the “nut rage” incident.

Seoul Western Prosecutor’s Office said Wednesday that Cho Hyun-ah faces charges including in-flight violence and changing a flight route.

The current airline executive, a 57-year-old man surnamed Yeo, faces charges of pressuring airline employees to cover up the incident, according to an official at the prosecutors’ office.

Cho, 40, the daughter of the Korean Air chairman, this month resigned as vice president at the airline and all roles from the its affiliates as public outrage mounted over her forcing a plane to return to a gate on Dec. 5 and kicking off a flight attendant because the nuts were served in a bag, not on a plate, in first class.

Prosecutors launched a probe over the incident after a citizens’ group filed a complaint against Cho. Last week, the Transport Ministry also reported Cho to prosecutors and said it will sanction Korean Air for pressuring employees to lie during a government probe.

Chang Man-yong, a Transport Ministry official, said the ministry had asked prosecutors to investigate a fellow ministry official suspected of leaking secrets about its probe into Yeo, the Korean Air executive charged with trying to cover up the incident. The official in question, surnamed Kim, worked at Korean Air for 15 years before getting a job at the ministry.

When as part of the ministry probe Kim questioned the crew member who had to leave the plane, Yeo sat next to the crew member, according to Chang. South Korean media said prosecutors raided Kim’s house and office, but the prosecutor’s office declined to confirm the reports.

Cho and her father apologized earlier this month, but a new furor has erupted over Korean Air’s attempt to foil government investigators. The public was also enraged because the Transport Ministry let a Korean Air executive sit in during the questioning of the crew member and because a majority of the ministry investigators formerly worked at Korean Air, the country’s largest carrier.
