The first female senior executive to ever hold a managing officer role with Toyota has resigned.

The uncharged Julie Hamp remains in custody in Japan after being accused of attempting to import Oxycodone from the United States. Japanese prosecutors have 20 days to charge Hamp. That window expires on July 8.

Toyota issued a statement today:

On June 30, 2015, Toyota Motor Corporation (TMC) received notification from Ms. Julie Hamp of her intent to resign her position of Managing Officer. TMC has accepted her resignation after considering the concerns and inconvenience that recent events have caused our stakeholders.

Senior Managing Officer Shigeru Hayakawa will act as Hamp’s interim replacement.
