Warning: The content of this story contains graphic details.

Kim Zolciak and Kroy Biermann’s son Kroy Biermann Jr. was seen looking stoic in his mug shot after being arrested for alleged sex crimes.

The 15-year-old, who goes by the nickname KJ, remained expressionless while wearing a black T-shirt in the booking photo taken by the Alpharetta Police Department and obtained by Page Six.

KJ was arrested for aggravated sodomy and aggravated sexual battery in Alpharetta, Georgia, on Wednesday.

According to court documents, a female classmate accused KJ of assaulting her in a gym changing area on April 23, claiming to authorities that he allegedly forced himself on her despite her saying no while they were in a co-ed sauna.

Per the filing, KJ allegedly attempted “multiple times to have sexual intercourse with her by trying to pull down her pants.” He is also accused of forcing oral sex and digitally penetrating her vagina.

The alleged victim “managed to get away from him,” after which KJ allegedly “pulled up his pants and left,” the filing claims.

The female classmate claimed she did not tell anyone about the alleged assault and went to school the following day, where she allegedly “ran into KJ’s girlfriend.” She allegedly fled the property and went to a Starbucks, where she contacted her family to let them know she was having a panic attack, court papers state.

She went to the North Fulton Hospital in Georgia for an examination on April 24. A police report states that there was no evidence of male DNA in her mouth or vagina, according to the examination.

KJ was taken into custody on Monday and is being held without bond at the Juvenile Court of Fulton County. He is scheduled to appear in court on Sept. 1.

The teen’s attorney, Jason Sheffield, claimed in a statement to Page Six that his client is “100% innocent” and that he “tried to present evidence to the arresting officer, including a passed polygraph by a notable and respected sex offender polygrapher,” and claimed he has “evidence of other prior false allegations by the alleged victim.”

“Additionally, the officer’s report notes [that investigators] found no male DNA on or inside the areas the alleged victim claimed she was assaulted. The fact that he’s been arrested and is being held without bond is a tragedy,” Sheffield said in part.

“He is not only presumed innocent, but is, in fact, innocent. I’m asking the public not to presume the truth of these allegations and to give the families on both sides their space and privacy,” his statement concluded.

His mom also addressed KJ’s arrest in an exclusive statement to Page Six on Friday.

“The allegations being made against my son are nothing short of reckless and deeply troubling,” the “Real Housewives of Atlanta” star’s rep told Page Six in a statement.

“He categorically denies ever being involved with this woman or engaging in the conduct she has alleged.”

The Bravo alum claimed her son voluntarily took a polygraph examination regarding the allegations and passed.

“Additionally, an examination was conducted, and no DNA belonging to my son was found,” the statement continued. She claimed, “We are also aware that this individual has made similar allegations involving two other people, which raises serious concerns that deserve to be carefully examined.”

Zolciak said in the statement that “false accusations” can have “devastating consequences” for the person being accused, as well as “for genuine survivors of sexual assault and abuse.”

“Every legitimate allegation deserves to be taken seriously and investigated based on the facts and evidence. At the same time, no one should be publicly condemned based solely on an accusation,” she wrote.

The statement concluded, “We remain confident that the facts and evidence will establish the truth, and we ask that people allow the proper process to take its course rather than spreading unproven allegations.”

Zolciak and her estranged husband, who have been locked in a contentious divorce since 2023, co-parent KJ and his siblings — Kash, 14, and twins Kaia and Kane, 12. Zolciak is also mom to daughters Brielle, 29, and Ariana, 24, from previous relationships.
