An American executive at Toyota Motor Corp. who was arrested for importing painkillers that are banned in Japan without a prescription appears not to have any health condition requiring their use, an investigative source said Saturday.

A routine health checkup conducted after the arrest of managing officer Julie Hamp on Thursday to examine her health status prior to detention showed she did not have any particular problem, the source said.

The first female managing officer at the carmaker was arrested on suspicion of importing the pills in violation of the drug law, and the case was sent to prosecutors Friday. She has denied the allegation.
