SAPPORO - Japanese police are questioning a zoo worker on suspicion of leaving a woman's body in an incinerator at the animal crematorium at Asahiyama Zoo in Hokkaido, an investigative source said Friday.

The man has told investigators that he put the body of his wife in the incinerator, the source said. However, as no such body has been found there, police are looking into whether it may have burned to ash.
