Julie Hamp, Toyota Motor Corp.'s first senior female executive who was appointed head of public relations just weeks ago, has resigned after her arrest for allegedly importing the prescription painkiller oxycodone in violation of the country's narcotics laws.

Toyota in a statement today said Hamp resigned Tuesday, and the company accepted her resignation "after considering the concerns and inconvenience that recent events have caused our stakeholders."

As Scott reported June 19, "A total of 57 pills were discovered by Japanese customs officials on June 11 inside a package that Hamp mailed to herself from Kentucky, declaring the contents to be a necklace." Oxycodone is legal in the U.S. with a prescription.

Hamp, who was arrested June 18, has denied the charges. She told authorities she did not think she had imported an illegal substance, police said. Prosecutors must decide whether to indict Hamp by July 8. She is in detention, but has not been charged with a crime.
