Death Note › Season 1

Chapter 11 — Assault

The Kira investigation team is discussing the disappearance of Naomi Misora when Watari interrupts their meeting. Sakura TV is broadcasting an audio tape which is allegedly from Kira. To prevent Kira from gaining public support, L demands that the broadcast be stopped. Hirokazu Ukita, one of the investigators working with L, rushes to Sakura TV but mysteriously dies in front of the station. The investigation team realizes that Kira no longer needs to know the person's name to kill and panics. Light, who is watching the broadcast from his room, concludes that he should involve himself in the Kira investigation to gather intelligence on L and the second Kira, whom he correctly infers has already accepted the shinigami eye deal. Meanwhile, L suspects that the person behind the broadcast must be a different Kira from the one they are chasing. (Source: Wikipedia)
