Reports say that three people, including BJ K and Juice Seyeon, have been booked by Gangnam Police Station in Seoul for alleged violations of the Narcotics Control Act involving psychotropic substances and are under investigation. Multiple reports stated that the two are suspected of taking sleeping pills classified as psychotropic drugs, and reported the booking date as July 30, 2026. However, booking is a procedure that records a person under investigation as a suspect, so this stage alone does not establish that drug use occurred or that a guilty verdict has been reached.

Key Development

Gangnam Police Station in Seoul told the media that three people, including BJ K and Juice Seyeon, had been booked without detention for alleged violations of the Narcotics Control Act involving psychotropic substances and were under investigation. Police reportedly changed the two from subjects of a preliminary inquiry to suspects. The key confirmed development is therefore not merely reporting about circumstantial information, but that the two have been booked as suspects and are undergoing a police investigation.

The allegations mentioned in multiple reports concern sleeping pills classified as psychotropic drugs. However, based only on the independently confirmed sources, the specific drug name, dosage, and exact circumstances of use cannot be established. Juice Seyeon’s individual position is also difficult to state definitively based on the information currently confirmed.

Booking marks the beginning of an investigation and is not a substitute for a court judgment.

Current Status

During a personal livestream on August 27, 2026, BJ K stated directly that he was involved in a case concerning a proxy prescription for sleeping pills and that he had been questioned by police. According to related reports, he is suspected of obtaining a proxy prescription through an acquaintance for sleeping pills classified as psychotropic drugs. His statement confirms that BJ K himself said he had been questioned by police, but it does not indicate that a final disposition has been reached or that a court has issued a ruling.

The currently confirmed status is as follows:

  • Three people, including BJ K and Juice Seyeon, have been booked and are under investigation.
  • The reported booking date is July 30, 2026.
  • BJ K stated that he was questioned by police in connection with a proxy prescription for sleeping pills.
  • No confirmed information has been found that the case has been referred, indicted, tried, or adjudicated.

According to an explanation from the Korean National Police Agency, booking is the procedure by which an investigative authority records a person under investigation in its case register and treats that person as a suspect under the Criminal Procedure Act. A non-custodial investigation proceeds without detaining the person. Accordingly, the term “booked without detention” means that the investigation is proceeding while the person is not being held in custody; it does not indicate whether the allegations are true or whether the person is guilty.

Implications

The key distinction readers should make in this case is between “allegations have been raised and an investigation is underway” and “guilt has been legally established.” Police booking is an important procedural development, but the investigative findings and subsequent judicial procedures remain pending. Reports about the individuals should also be examined separately according to the investigation details released by police, the allegations reported by the media, and the statements directly confirmed by BJ K.

In particular, the individual actions of the two people and the specific circumstances of the case should not be inferred beyond what has been confirmed. Based on the current material, the confirmed facts are that Gangnam Police Station in Seoul is investigating three people in connection with the allegations; that the two are suspected of involvement with sleeping pills classified as psychotropic drugs; and that BJ K stated he had been questioned by police regarding a proxy prescription.

Next Checkpoints

The points to monitor going forward are the progress of the police investigation and the next procedural steps. The general process described by the Korean National Police Agency may include referral after a non-custodial investigation, indictment, and trial, but it has not been established that this case has reached any of those stages. Follow-up reporting should therefore focus on official announcements from Gangnam Police Station, dispositions announced by investigative authorities, and any additional statements directly confirmed by the individuals involved.

The current status can be updated by checking the following:

  1. Whether Gangnam Police Station in Seoul has announced the progress of the investigation or a subsequent disposition.
  2. Whether BJ K has directly disclosed additional details about the circumstances of the case or the investigation results.
  3. Whether Juice Seyeon has officially released an individual statement.
  4. Whether new procedures, such as referral, indictment, or trial, have actually begun.

At present, the confirmed scope extends to booking and the police investigation stage. The specific drug name and dosage, the exact circumstances of use, and any final determination of guilt are matters that must be confirmed separately through the subsequent investigation and judicial process.
