A retired Honolulu Police Department sergeant who had been working as a driver’s license examiner was arrested today for allegedly sexually assaulting a woman during a road test.

Corbett Roy, 59, was charged with three counts of fourth-degree sexual assault and a single count of harassment. He was released after posting $1,000 in aggregate bail.

The abuse allegedly occurred on Sept. 20 during a road test administered in Kaneohe.

The victim initially complained at the driver’s licensing center. She later filed a police report.

HPD Deputy Chief John McCarthy confirmed today that Roy had served with the department for 31 years, mostly as a patrol officer. Roy retired as a sergeant in 2011 and stayed on as a reserve-duty officer until last year.

Roy has no prior arrests.
