A Brazilian suspect in Ota City, Gunma Prefecture, was arrested by the police for selling cannabis at home.
The police are investigating the details of the situation, as they were informed by changing the color of the outside light at the entrance to ``blue'' during the hours of trafficking.
De Souza Hashimoto Mateus Kenji (28) from Ota City, Gunma Prefecture, is suspected of violating the Anti-Drug Law.
According to investigative sources, the suspect was arrested and indicted for selling cannabis and illegal drugs to five people last year. He was prosecuted on suspicion of violating the Special Drug Law.
The suspect was allegedly trafficking cannabis at his home, but investigators say he signaled customers by changing the color of the lights outside his front porch.
Specifically, it is said that outside lights were turned on blue when conducting trafficking, and turned red or turned off when they could not respond.
In addition, if there is a reservation in advance on SNS, it is believed that unmanned sales were also conducted in the form of putting cannabis etc. in an unlocked mailbox and having cash left.
He has admitted to the allegations against the investigation.
It is believed that the money obtained from trafficking was used for living expenses as well as travel and purchase of branded goods, and the police are investigating the detailed situation, assuming that tens of millions of yen were sold.
