BTS comeback show sells out immediately as 260,000 fans set to descend on Seoul

Booking system freezes and screens crash amid rush of fans trying to secure tickets to 21 March free concert

Tickets for BTS's comeback concert in central Seoul were snapped up almost immediately on Monday night, with authorities expecting an estimated 260,000 fans to descend for the K-pop group's first full performance in nearly four years.

At one point, more than 100,000 people flooded the booking website when sales opened at 8pm for the free concert at Gwanghwamun square on 21 March, causing screens to crash and booking systems to freeze.
