Cambodia has released a South Korean man arrested in April on charges relating to the disappearance of a female North Korean restaurant employee, a government official said Tuesday.
The 35-year-old, surnamed Kim, arrived in Seoul earlier in the day after Cambodian authorities decided to release him for lack of evidence, the official said on condition of anonymity.
According to the Yonhap news agency, Kim was arrested on April 25 at Phnom Penh airport on suspicion of human trafficking and sexual exploitation.
A former North Korean refugee who became a South Korean national, he had been sought by Cambodian police after a 25-year-old North Korean woman, who was last seen leaving a hotel room with Kim, went missing in June last year.
North Korean diplomats claimed the woman had been kidnapped.
Cambodia has diplomatic relations with both North and South Korea.
The North has opened restaurants under local franchises in several countries. They are seen as a useful source of scarce foreign currency for the cash-strapped regime.
