Allegations against BLACKPINK member Jisoo’s brother resurface amid sexual assault case investigation

Allegations involving the brother of BLACKPINK member Jisoo have resurfaced online following renewed attention to a separate sexual assault-related case involving a man identified in Korean media as her sibling.

According to reports from South Korean media outlets, past accusations against a man surnamed Kim, identified as Jisoo’s older brother, have been brought back into public discussion after news emerged of his arrest in connection with sexual misconduct allegations involving an internet broadcaster (BJ).

The original allegations date back to May last year, when an anonymous post appeared on the workplace community platform Blind. The writer claimed they had engaged in a consensual relationship with Kim but later discovered they had been secretly filmed without consent. The post further alleged that the individual in question showed the footage to acquaintances and possessed additional illicit recordings involving other women. The poster stated at the time that they were considering legal action.

Kim’s side denied the allegations, describing them as “entirely false,” and indicated that legal action would be pursued in consultation with legal representatives. The post was subsequently removed from the platform.

The issue has resurfaced following reports that a man identified as Kim was arrested on April 15 on charges of indecent assault, along with additional allegations under South Korea’s Sexual Violence Punishment Act, including offences related to the use of illegally recorded material and threats involving distribution of such content.

According to police statements cited in local reports, the victim alleged that Kim shared intimate images she had received with third parties and later used them as leverage to issue threats. Investigators from the Seoul Gangnam Police are reported to have applied for an arrest warrant as the investigation continues.

Reports also indicate that Kim met the alleged victim after purchasing a “dinner date” event through the livestreaming platform SOOP. It is alleged that after meeting on April 14, he took the victim to his residence following assurances that no harm would occur, before attempting inappropriate physical contact.

During police questioning, Kim reportedly acknowledged that physical contact occurred but denied that it was non-consensual. Authorities have stated that investigations are ongoing.
