LOUISVILLE, Ky. (WDRB) -- A Lexington, Indiana, man has been arrested after investigators say he engaged in sexual activity with a 15-year-old girl in Scott County.

According to a probable cause affidavit, 32-year-old Bob Auer is accused of giving the 15-year-old marijuana and fondling her sexually. Police say he also sent pornographic images to her via Facebook Messenger. Investigators were able to view messages between Auer and the victim by searching her school-issued MacBook, after obtaining permission from her parents and the school's principal, according to court documents.

When confronted by the allegations on Dec. 16, Auer allegedly told officers that he accidentally sent the nude images to the 15-year-old, and meant to send them to another person named "Jessica," but could not provide her full name or place of residence. He also denied engaging in any sexual physical contact. He later declined to answer any more questions, according to the probable cause affidavit.

Auer is charged with engaging in sexual misconduct with a minor, dissemination of matter harmful to minors and contributing to the delinquency of a minor. He is currently being held in the Scott County Detention Center.
