Police Detain Man in Seoul Molestation Probe; Online Speculation Names Jisoo's Brother, Unconfirmed

Korean media reports dated April 16 said the Gangnam Police Station in Seoul had detained a man in his 30s on a charge of forced molestation. Police have opened an investigation. They have not officially confirmed who the accused is.

The complaint comes from a female streamer. According to the reports, the man had bought what is described as a "date ticket" to spend time with her. The two reportedly met for a meal and drinks, and he then invited her to his home, assuring her he would not engage in any inappropriate behaviour. The situation allegedly escalated once they arrived there.

Koreaboo, a Korean outlet, cited the complainant as saying he promised there would be no sexual contact, that she rejected him several times, and that he forced physical contact and also tried to sexually assault her. She further alleged that he had been drinking and drove under the influence before the incident. Police reportedly intervened after the situation was reported, and the woman was assisted at the scene.

The case then took a turn that has little to do with what police have said. Soon after the reports appeared, online speculation tied it to Kim Jung-Hoon, the elder brother of BLACKPINK's Jisoo. Police have issued no confirmation of any involvement on his part. His name spread on social media after netizens matched details from the case against publicly available information.

The speculation was fueled further when a Korean news platform used a blurred image of Jisoo and her brother in a thumbnail. Online users took it as a pointer, identified the people pictured, and connected them to the investigation. As a result, Jisoo's name has been drawn into the discussion, though nothing in the reporting suggests she has any involvement in the case.

Kim Jung-Hoon is six years older than Jisoo and is publicly known mainly through her professional ventures. He is reportedly connected to her label, BLISSOO, is said to have been a founding member, and has credits linked to her performances. He is also reported to be married with two children.

His name has surfaced in controversy before. In May 2025, an anonymous post on a workplace community platform, titled "I was secretly filmed by BLACKPINK Jisoo's brother," alleged that a woman had been secretly filmed without consent during an assault and that the video was shared with others. The post was later deleted, and no official findings were publicly confirmed in connection with those allegations.

What matters now is what police say next: whether they formally identify the detained man, and whether the case moves forward. Until then, the only confirmed facts are the detention, the charge, and the complainant's account. The link to Jisoo's family remains online conjecture.
