(CNN) -- A musician who played in the 1970s pop music group KC & the Sunshine Band was in court Friday to face an indictment on 16 sex charges involving "multiple male juveniles," an Ohio prosecutor said.

Richard Finch was arrested last month in Licking County, Ohio, after a 17-year-old boy said he had sexual contact with him. Investigators said they were looking into other possible victims.

A grand jury indictment this month charges Finch with 10 counts of sexual imposition. Assistant prosecutor Tracy Van Winkle said the charges involve having sex with someone when it is harmful to them.

Finch also faces three counts of compelling prostitution involving offering money to minors for sex, Van Winkle said. Two counts involve asking a minor to engage in sex, and one count is a charge of sexual contact with a minor, she said.

A teenager said he had sexual contact with Finch at Finch's house in Newark, Ohio, the Licking County Sheriff's Office said in a statement after the arrest.

During an interview with detectives, Finch "disclosed that he did in fact have sexual contact with the juvenile, along with multiple other male teenage juveniles as well ranging from ages 13 to 17," the office said.

A pretrial hearing will be held Friday. Finch is in the Licking County jail; no trial date has been set, she said.

A statement from Finch and his lawyer was posted on his website soon after his arrest: "They would like to remind everyone that these are just allegations and that Mr. Finch is presumed innocent."

A more recent posting asking fans to donate to his legal defense fund said Finch had to cancel his plans for "an impending tour" and "a catastrophic economic hardship has taken their place."

"Those revenue generating possibilities are now gone, and as of this time, Mr. Finch's attorneys are in the early stages of their investigation," it said.

Finch played bass and drums with KC & the Sunshine Band. The group is known for hits such as "That's the Way (I Like It)," "Get Down Tonight" and "I'm Your Boogie Man." He co-wrote many of the band's biggest hits with Harry Wayne "KC" Casey. He left the band in 1980.

Casey disputed that Finch co-founded the band, saying that he started it in 1973 and Finch joined a year later. However, singles from the band's first album, "Do It Good," were released in 1973 and feature Finch.
