South Korean singer Bobby Kim was investigated by the FBI for an alleged sexual harassment of a female crew member on a flight from the northwestern city of Incheon to San Francisco, local media reports said Friday. The incident took place on the U.S.-bound Korean Air Lines Co. plane on Wednesday.

The 41-year-old hip-hop artist is accused of inappropriately touching the crew member and also verbally abusing her after getting intoxicated. The singer reportedly yelled at the flight attendant, five hours after the plane took off from Incheon. A complaint was filed against Kim, who was later taken for questioning by FBI and airport security, upon landing at San Francisco International Airport, Seoul-based Yonhap News Agency reported. FBI also reportedly questioned two other crew members and two passengers who were seated next to Kim.

"Kim had been upset when he was drinking wine (served during the flight)," the singer's management agency reportedly said, adding that he was angry as he was mistakenly seated in economy class even though he had earlier requested for an upgrade to business class. "He says he doesn't remember exactly what he did on that flight," the agency added.

South Korean police reportedly said that they would investigate the matter as soon as Kim returns to the country, following the FBI probe in San Francisco.
