A Japanese government official was temporarily detained in South Korea for allegedly assaulting an airport worker in Seoul while on a personal trip, the government said Wednesday.

Kosuke Takeda, a 47-year-old official of the Ministry of Health, Labor and Welfare, is suspected of assaulting a worker at Gimpo International Airport and telling the worker that he hates South Koreans, according to a senior ministry official.

South Korean police said Takeda was detained Tuesday on suspicion of hitting an airport worker at a boarding gate while under the influence of alcohol.
