K-pop group BTS drew 840,000 fans across 15 performances in five cities for the North American leg of its world tour, the group's agency said Saturday.

The seven-member act performed sold-out shows recently in Tampa, El Paso, Stanford and Las Vegas in the United States, as well as Mexico City in Mexico, as part of its "Arirang" world tour, according to BigHit Music.

Due to overwhelming demand, the group put on extra shows in Tampa, Stanford and Las Vegas, which all sold out.

BTS began the world tour last month to mark its comeback after a near four-year hiatus as members fulfilled South Korea's mandatory military service for men.
