HONOLULU (AP) - Honolulu’s acting prosecutor says he’s been subpoenaed to testify before a federal grand jury.

Dwight Nadamoto stepped in as Honolulu’s top prosecutor after Keith Kaneshiro received notice from the FBI that he’s a target in an investigation. Kaneshiro denies any wrongdoing.

A federal corruption probe brought down one of Kaneshiro’s former deputies, Katherine Kealoha, and her now-estranged husband, former police chief Louis Kealoha.

A jury convicted the Kealohas of conspiracy in a plot to frame her uncle to hide fraud that financed the couple’s lavish lifestyle. They also pleaded guilty to bank fraud. Katherine Kealoha pleaded guilty to identity theft and a drug-related charge.

Nadamoto says he can’t discuss the subpoena he received Monday. He says he’ll comply with the subpoena and is happy to answer questions federal authorities have.
