This is the second time since last year, an AISD employee was charged with sexual assault.
In June of last year, Austin ISD officials said an elementary school teacher was charged with aggravated sexual assault of a child.
33-year-old Alfredo Andrade-Gaytan was arrested for aggravated sexual assault of a 6-year-old at Reilly Elementary and two counts of indecency for touching an 8-year-old girl and a 9-year-old girl.
According to the affidavit, the incidents regarding the two counts of indecency took place at Walnut Creek Elementary School.
