Japan's Kyodo News says the American Toyota executive who was arrested last month on suspicion of drug law violations is expected to be released Tuesday without being prosecuted.

Kyodo did not identify the source of its information. Tokyo prosecutors declined to comment and Toyota Motor Corp. said it had no information.

Julie Hamp, 55, who was the highest ranking woman executive at the Japanese automaker, was arrested June 18 on suspicion of bringing in oxycodone, a narcotic pain killer, into Japan. The drug is tightly controlled here.

She has not been available for comment. But police say she has denied trying to import an illegal drug. Toyota Chief Executive Akio Toyoda has said he believed Hamp had no intention of breaking the law.
