Nippon TV News named the suspect as Kurokawa Takumi. Citing the Metropolitan Police Department, it said he allegedly conspired with accomplices in May this year to enter a precious-metals buying shop in Shinjuku Ward, Tokyo, and steal a safe containing precious metals with a market value of about 25 million yen, along with cash. He is believed to be a “case broker” who conveyed information about the site to a theft group, and two men from that group were also arrested, the outlet reported. [ 3 ]
The theft group is believed to have cased the scene of a robbery-murder at a house in Kaminokawa Town, Tochigi Prefecture, in May this year, according to Nippon TV News. The outlet said the Metropolitan Police Department has not disclosed whether Kurokawa admits the allegations and that investigators are continuing to look into who directed the crimes. [ 3 ]
The three outlets published their reports within about 15 minutes of one another on the evening of October 7, 2026, with Tokyo Shimbun first. Tokyo Shimbun’s feed item carried no article text about the arrests beyond its headline. [ 1 , 2 , 3 ]
Why it matters
The arrests focus attention on the role of information brokers who pass site details to theft groups, which police are treating as part of this case. Nippon TV News also links the theft group to the casing of a robbery-murder scene in Tochigi Prefecture, suggesting the investigation may reach beyond property crime. The documents give no further indication of the case’s wider scale.
