A Salt River police officer is facing charges for allegedly kidnapping and sexually abusing a woman he had in his custody back in March.

Officer Jay Hun Wu, 45, was arrested by Scottsdale police on Thursday.

According to police, the woman was with Wu because she was the subject of a criminal investigation. Officer Wu agreed to give the woman a courtesy ride back to her apartment.

The woman told the officer he could drop her off in front of her apartment. Instead, Wu allegedly kept driving and would not let the woman out despite her repeated requests for him to stop, said police.

Court paperwork stated GPS tracking on Wu's car confirmed the victim's allegations that he continued driving past her residence.

Instead of dropping her off near Via Linda and Shea Boulevard, he drove to 96th Street and Via Linda--over 2 miles away--and stopped the car next to a wall. Police said he went to the backseat, opened the door, and told the victim he needed to "pat her down" and then touched her chest and buttocks underneath her clothing.

He then gave her his business card and "requested that she call him if she needed anything," according to police.

During a "confrontation call" between Wu and the victim organized by Scottsdale police, Wu did not deny the allegations and repeatedly apologized to the victim, court documents show.

Wu was arrested and booked into jail. He faces charges of kidnapping, sexual abuse, unlawful sexual conduct of a peace officer, assault and tampering with physical evidence.
