Kim Zolciak and Kroy Biermann’s teenage son, Kroy Jr., has been arrested on allegations of aggravated sodomy and aggravated sexual battery after a female classmate accused him of assaulting her in a gym changing area.
According to Fulton County, Georgia, Juvenile Court documents obtained by TMZ, 15-year-old Kroy Jr., who is known as KJ, was arrested Monday in Alpharetta, Georgia. The charges stem from an alleged incident on April 23.
The court papers state that the alleged female victim told authorities she was at a gym when she saw KJ, and that the two later entered a co-ed sauna.
The girl claimed KJ began touching her after she said no. She further alleged that he forced her to perform oral sex and tried “multiple times to have sexual intercourse with her by trying to pull down her pants.”
In the documents, she alleged that when she “finally managed to get away from him … he pulled up his pants and left.”
An officer was sent to North Fulton Hospital on April 24, 2026, following a report of a sexual assault.
