Thomas Shell Jr., 63, was taken into custody Wednesday night around 10:30 p.m.
This comes after a sergeant with the Knox County Sheriff's Office opened an investigation into shell back in August.
A detective with the case determined there was probable cause based on allegations of misconduct that stemmed back to 2006.
Those allegations involved a victim under the age of 12 and had been on-going since that time.
Shell was charged with two counts of gross sexual assault and one count of unlawful sexual contact.
He was taken to the Knox County Jail
