Reports that Japanese sushi chef Kenji Fujimoto has been detained in North Korea are currently unconfirmed, a Japanese intelligence official told NK News on condition of anonymity on Wednesday.

Fujimoto, Kim Jong Il's former sushi chef, may have been put in custody in Pyongyang for selling information to the Central Intelligence Agency (CIA) which he had obtained after visiting North Korea in 2012 and 2016, Japan's Daily Shincho said earlier on Wednesday.
