A handshake event for the idol group Keyakizaka46 was set on fire by a man who later admitted he wanted to kill one of its member.
The event occur on June 24 at Makuhari Messe in Chiba City.
A flare was ignited at the event's designated baggage storage area. The fire department was called to the scene, but the flames were put out by staff members with fire extinguishers.
A 24-year-old male suspect named Ryo Abe was arrested in relation to the incident. After being apprehended, he was found to be in possession of a paring knife.
According to reports, Abe admitted to official that he wanted "stab and kill" a member of Keyakizaka46. The identity of the idol he was targeting has not been released.
The incident temporarily caused the event to be stopped due to security concerns. After officials cleared the area, the event resumed, though the lane affected by the flare was not reopened.
No injured occurred as a result of the incident.
The failed murder attempt bears similarities to past stabbing of idols. In 2014, an AKB48 event was terrorized when a man began slashing at the group with a saw, leaving 5 people injured, including group members Rina Kawaei and Anna Iriyama.
