21-year-old talento Koji Hirano has been arrested on suspicion of lewd acts with a minor. Hirano is one of the five members of BLuck, a male idol group active in Hokkaido that formed in 2004.

According to investigators, Hirano met a 17-year-old girl from Sapporo through a mobile phone site, and is suspected of committing sexual acts with her at her home in mid-January. Hirano has denied the charges.

BLuck's agency says they are also gathering more information about the matter. According to the group's website, BLuck is currently suspending their activities.
