Dustin Young, 36, of Trenton, was indicted in April by a Butler County grand jury for gross sexual imposition, kidnapping and two counts of abduction.
He appeared in front of Oster on Wednesday morning along with his attorney Dan Haughey and made the motion for a bench trial.
Oster held up the signed document presented to him asking for the bench trial and asked Young if he understood that he would be releasing his rights to have his case "heard by a jury of your peers."
Young responded that he was clear on his decision and had indeed decided to not have a jury trial.
Both the prosecution and defense agreed that the Oct. 10 trial date can proceed without delay.
The alleged sex crimes committed by Young occurred between Aug. 1 and Nov. 12, 2016, according to documents obtained by this news outlet.
The woman alleges that Young pulled her into his lap and touched her crotch and pinned her against lockers on two occasions, according to documents.
Young is also accused of grabbing a woman's buttocks at least 40 times.
A grand jury report said Young "(had) sexual contact with another...cause another to have sexual contact...or cause two or more persons to have sexual contact...by force or threat or force," from Aug. 1 through Oct. 22. The report also said Young used "force threat or deception" to kidnap someone. The abduction charges are dated Aug. 1 and Nov. 12.
Young, who was a sergeant, resigned from the department on Jan. 11. He was placed on administrative leave on Nov. 22, 2016, according to an internal report reviewed by this news outlet.
Another person interviewed by police said Young drove the woman to the university airport multiple times in an attempt to have sex with her.
The Hamilton Police Department conducted the criminal investigation that resulted in a direct indictment on April 26, which was sealed until Young's arrest.
