Two sisters who are principal and vice principal of the Myron B. Thompson Academy state charter school turned themselves in to state sheriff deputies Tuesday. The women have been under investigation by the state attorney general for more than two years.

The deputies booked Principal Diana Oshiro and elementary school Vice Principal Kurumi Kaa- pana-Aki on suspicion of tampering with a government record and Kaapana-Aki on suspicion of theft. They then released the sisters without charges.

The state Department of the Attorney General has been investigating the school since at least November 2013 when it asked a state judge to order the state Ethics Commission to turn over records of its investigation of Oshiro and Kaapana-Aki.

The Honolulu Star-Advertiser was unable to reach Oshiro, Kaapana-Aki or their lawyers for comment.

Deputy Attorney General James Walther said the department could not provide information about the arrests Tuesday evening.

State Public Charter School Commission Chairwoman Catherine Payne said the commission is concerned. “However, the governing board of the Myron B. Thompson Academy must first be allowed to address this issue. The commission will be following up with the governing board,” Payne said.
