COLUMBIA, S.C. -- A former youth minister at a South Carolina church has been arrested and charged with sex crimes involving three people.

Multiple media outlets reported that 30-year-old William Ralph Wilson of Gaston was arrested Thursday on four charges. Lexington County sheriff's deputies charged Wilson with two counts of committing a lewd act on a minor and two counts of exposing minors to sexually explicit materials.

Wilson is the former youth minister at Chapel of Redemption Church in West Columbia.

Three victims made complaints about Wilson to the department this week.

Maj. George Brothers says all the activities occurred at Wilson's home, starting in late 2007. All three people had attended Chapel of Redemption Church.

Wilson was being held at the Lexington County jail. It was unclear if he had an attorney.
