Kroy Biermann Jr., known as KJ, the 15-year-old son of former The Real Housewives of Atlanta star Kim Zolciak and retired NFL player Kroy Biermann, was arrested August 17 in Alpharetta, Georgia.
According to court documents reported by TMZ, the arrest followed an investigation into an alleged April 23 incident at a Life Time Fitness facility.
The Arrest Came Months After the Alleged Gym Incident
Authorities say the alleged victim was a teenage classmate of KJ’s. The incident was reported to police the following day, when an officer was dispatched to North Fulton Hospital after the girl and her father reported an incident.
Police then began investigating what had happened at the gym and gathering information from the people involved. The allegations are disputed, and KJ has not been convicted of any crime.

The Investigation Stretched Into May
After the report was made, investigators began working to establish what happened and to speak with KJ’s family. An officer reportedly first attempted to contact Kroy on May 14. Four days later, Kroy spoke with the officer and said he would discuss the matter with Kim, according to the police report.
The investigation also included a medical examination of the alleged victim. The police report states that doctors did not find male DNA in the areas examined, a detail that would later become central to KJ’s family’s public response.
Kim Was Still Celebrating Her Son Weeks Before the Arrest
The allegations surfaced publicly months after Kim had shared an emotional birthday tribute to KJ. On May 31, she described him as her “most incredible son” in an Instagram post and wrote at length about her pride in the teenager, particularly his work ethic, discipline and dedication to football.
“I had no idea what was missing from my life until you arrived. You changed me in ways I could never fully describe. ❤️ You taught me strength, compassion, patience, and what the mother-son bond truly means.”
She added, “You are my heart walking outside of my body, and every day you amaze me. You give the biggest, best hugs, and I am so proud of the young man you have become.”
