Honolulu Police Department (HPD) commander Ryan Nishibun has been demoted following allegations that he shared confidential information regarding a teen sexual assault victim, including the victim’s name and personal details. The incident has sparked concern over protocol and victim protection within the department.
Nishibun, a 35-year veteran of the HPD, was removed from his position as acting deputy chief of field operations on Sunday, March 1, 2026 and reassigned to the role of assistant chief of the administrative bureau, according to an internal HPD memo. The allegations center around Nishibun allegedly providing the sensitive information to a friend, which subsequently appeared on social media. This breach of confidentiality has drawn sharp criticism from within the law enforcement community.
Details of the Alleged Information Leak
Retired HPD deputy chief John McCarthy described the alleged conduct as “such an egregious offense,” emphasizing the heightened protections afforded to juveniles. “Releasing juvenile names is just an absolute no-no,” McCarthy stated. He explained that disseminating such information compounds the harm to the victim, potentially exposing them to ridicule, questioning, or bullying. The incident highlights the critical need to safeguard the privacy of vulnerable individuals involved in sensitive investigations.
According to reports, the confidential information included the victim’s name and other personal details. The HPD has confirmed the launch of an internal administrative investigation into the matter, but stated that the specifics of the allegation will not be disclosed to avoid compromising the ongoing inquiry. Nishibun could face further disciplinary action beyond the demotion, pending the outcome of the investigation.
Leadership Changes and Protocol
Nishibun had been serving as the acting deputy chief of field operations since August, following the retirement of Keith Horikawa. Prior to that, he served as the commander of the Central Patrol Bureau, overseeing Waikiki, since 2021. Currently, Rade Vanic is serving as the Interim Chief of Police for the Honolulu Police Department, according to city records.
The HPD protocol dictates that any further discipline beyond the demotion must be recommended by the two deputy chiefs reporting to Nishibun, with the final decision resting with the chief of police. This process ensures a level of oversight and due process in addressing the allegations.
Impact and Ongoing Investigation
The alleged leak raises serious questions about data security and confidentiality practices within the HPD. The department’s internal investigation will likely focus on how the information was accessed, shared, and ultimately ended up on social media. The incident underscores the importance of robust training and strict adherence to protocols regarding sensitive information.
The HPD’s handling of this situation will be closely watched by the public and legal observers. Maintaining public trust requires transparency and accountability, particularly in cases involving vulnerable victims. The outcome of the internal investigation and any subsequent disciplinary actions will be crucial in demonstrating the department’s commitment to protecting the privacy and well-being of those it serves.
What comes next is the completion of the internal administrative investigation. The findings will determine whether additional disciplinary measures will be taken against Nishibun. The HPD has not provided a timeline for the completion of the investigation.
