Police said Wednesday they will set up a crowd control zone with a capacity of 100,000 people around the stage where K-pop group BTS will perform in central Seoul this weekend. The zone will be set up so that no more than one person occupies every square meter, as safety is of paramount importance during the concert set to begin at 8 p.m. Saturday at Gwanghwamun Square, an official at the Seoul Metropolitan Police told reporters. Police expect around 260,000 people to gather in the area
