Police have launched an investigation after detecting criminal activity linked to BTS's upcoming comeback concert.

Park Jeong-bo, Commissioner of the Seoul Metropolitan Police Agency, addressed the issue during a regular press briefing on March 9 at the agency headquarters in Jongno District, Seoul. Authorities shared their response plans for the BTS performance scheduled for March 21.

Police are currently investigating three suspected criminal cases. Officials said they suspect large-scale ticket purchases using macro programs and have opened an inquiry. Complaints related to ticket transfers are also under investigation.

Fraudulent Resales of Free Tickets

NOL Ticket, the official ticket distributor for the event, reported suspicious activity to police. Authorities discovered cases in which free concert tickets were fraudulently resold for hundreds of thousands of KRW.

Police have been actively monitoring illegal ticket sales related to the BTS concert. Approximately 110 online posts advertising proxy ticket purchases or similar services have already been requested for removal or blocking.

Massive Crowd Control Operation Planned

Authorities are also preparing extensive safety measures for the concert day. Police estimate that up to 260,000 people could gather around the Gwanghwamun area.

To manage the crowd and prevent accidents, about 4,800 police personnel—including mobile units—will be deployed.

HYBE will also strengthen on-site safety management. The company plans to assign approximately 4,300 staff members around the venue to assist with crowd control and maintaining order.

Meanwhile, BTS will release their fifth full-length album ARIRANG on March 20 at 1 p.m. KST. The group will debut the new songs live for the first time at Gwanghwamun Square on March 21.
