Authorities said Wednesday 30-year-old Andrew Alan Haney had been charged with interstate commerce of obscene materials to a person under 16.
Police say Haney met the girl in Polk County, Iowa, through a social media website last month.
Authorities say they identified Haney as a suspect after he sent the girl a photo with his police badge with the state seal visible in the photo.
West Columbia Police Chief Dennis Tyndall says Haney has been fired from the force. Haney was expected in court Thursday, and it wasn’t clear if he had an attorney.
