A 44-year-old Sunday school teacher has been charged with criminal sexual assault after police accused him of having sex with a 15-year-old girl in a Decatur church and having nude photos of her.

Christian Coady of Decatur is charged with six counts of criminal sexual assault, five counts of aggravated criminal sexual abuse and two counts of child pornography. He's being held on $250,000 bond at the Macon County Jail.

Coady hasn't yet entered a plea, and his attorney, Jeff Justice of Decatur, declined to comment.

Police say Coady taught at the East Park Baptist Church and had been having a relationship with the girl for about a year.
