A 27-year-old man in Japan has been arrested over a Nintendo HQ bomb threat after letters sent to the company’s Kyoto headquarters claimed explosives had been planted there, according to KTV.

Police took the man, who lives in Hekinan City in Aichi Prefecture, into custody on May 12 on suspicion of sending threats to Nintendo. The case has the grim modern rhythm of entertainment news: beloved company, alarming message, police search, no explosives found. Not exactly the kind of tension anyone ordered.

What the threatening letters said

The envelope arrived at Nintendo’s headquarters in Kyoto on March 13. Inside were messages that included: “I’m going to blow you all up” and “My plans can not be thwarted.”
