Kim Zolciak and Kroy Biermann Son Arrested on Felony Sexual Assault Charges
Kroy “KJ” Biermann Jr., the 15-year-old son of former Real Housewives of Atlanta star Kim Zolciak and former NFL player Kroy Biermann, was arrested on Monday, Aug. 17, by Alpharetta police on felony charges of aggravated sodomy and aggravated sexual battery following an alleged assault against a female classmate at an Atlanta-area Life Time Fitness facility.
Court Documents and Police Investigation Timeline
According to Fulton County Juvenile Court documents and local police reports, the alleged incident took place on April 23. An officer was dispatched to North Fulton Hospital the following day, April 24, 2026, after the 15-year-old victim and her father reported a sexual assault. Investigators state that the female classmate told authorities she was hanging out at the gym when she saw KJ Biermann, who suggested they visit the co-ed sauna. To access the sauna, the two walked through a family changing room.
In the police report, the victim claimed that KJ Biermann began to touch her inappropriately and ignored her repeated refusals. She alleged that he forced her mouth on his penis and digitally penetrated her vagina before she managed to escape the room. Law enforcement later reviewed surveillance footage confirming that the younger Biermann was present at the facility on the date of the encounter. According to TMZ, an officer attempted to contact Kroy Biermann Sr. on May 14 regarding the case, speaking with him on May 18, at which point the father stated he would discuss the matter with Kim Zolciak.
Medical Findings and Defense Statements
Police records indicate that the victim suffered a panic attack upon seeing the suspect’s girlfriend at school the day after the incident and subsequently disclosed the assault to school officials. Following the hospital evaluation, medical examinations of the accuser yielded no male DNA in her mouth or vagina, according to police documentation outlined by TMZ.
Kim Zolciak issued a lengthy statement on Friday, vigorously defending her son and dismissing the charges. “The allegations being made against my son are nothing short of reckless and deeply troubling,” Zolciak told TMZ. “He categorically denies ever being involved with this woman or engaging in the conduct she has alleged.” Zolciak also claimed that her son had voluntarily passed a polygraph test.
Family Turmoil and Legal Proceedings
The felony arrest compounds ongoing familial distress for the household. Kim Zolciak and Kroy Biermann have spent months engaged in a highly litigious and public divorce, trading accusations regarding financial stability and parenting fitness since their marriage in 2011.

KJ Biermann is currently being held without bond at the Metro Regional Youth Detention Center. Legal records show that a preliminary hearing in the case is scheduled for Sept. 8. Attorneys representing the family have not yet released specific details concerning their anticipated defense strategy.
