Saitama police have arrested a 31-year-old company employee from Aichi Prefecture on suspicion of soliciting participants for a violent robbery that occurred last month in the city of Tokorozawa, Saitama Prefecture.

According to investigative sources, Yuya Nagura, from the city of Chita, has admitted to the allegations, saying, "I was in charge of introducing new people. I did it because I needed the money."

The sources said that Nagura used social media to post advertisements with phrases like "easy job" and "goods transport" to recruit individuals for "dark part-time jobs," known as yami baito in Japanese. He then exchanged messages with applicants via encrypted messaging apps such as Signal and Telegram, ultimately introducing these recruits to another individual believed to have directed the operations.
