Christopher Hays, 30, is charged with five counts, including felony false imprisonment and misdemeanor sexual battery. He faces up to three years and eight months in state prison if convicted.
Hays pleaded not guilty today at his Superior Court arraignment.
Three women testified at a preliminary hearing last month, alleging they were groped after being contacted and searched by Hays, a four-year SDPD veteran who resigned the day after he was charged in February.
A fourth woman alleged that Hays groped her after her arrest for shoplifting, according to SDPD Detective Cory Gilmore.
In his ruling ordering the defendant to stand trial, Judge Charles Rogers found that the alleged victims who testified were "credible, truthful and accurate."
Hays remains free on $130,000 bail. A status conference is scheduled July 18.
