Thai officials will soon travel to Cambodia after an adviser to a Japanese man claiming to be the father of at least 15 babies in Thailand on Friday invited them to see how well four children apparently fathered by the man are being raised in Cambodia.

Assistant National Police Chief Kokiat Wongworachart, in a news conference in Bangkok, referred to the adviser as the man's "coordinator" and said the coordinator had sent police photographs of the children in Cambodia showing they are in good health.

Still, the assistant chief said, Thai authorities need to check on them in person.
