A Honolulu police major facing federal extortion charges is asking that his GPS monitoring device be removed from his ankle for medical reasons.
Carlton NIshimura faces federal charges of extortion, lying to investigators, witness tampering and drug possession. He is awaiting trial.
A Wednesday hearing is scheduled for his motion to modify conditions of pretrial release.
Federal Public Defender Peter Wolff's motion asks that the GPS requirement be eliminated because of a doctor's letter saying it's contributing to a condition that requires medication that has a negative effect on NIshimura's cognition.
The motion says he needs to eventually get off the medication to prepare for trial.
Assistant U.S. Attorney Thomas Muehleck opposes eliminating GPS monitoring, noting that he is already allowed to leave his parents' Waianae home for special reasons.
