Two suspects in their 300s were arrested for making "ole ole scam" calls based at a hotel in Chiba Prefecture and defrauding an elderly person of 20 million yen in cash.
A report from a hotel guest that "I heard what sounded like a scam phone call" led to the arrest.
Two suspects were arrested: Mikiya Yamamoto (29), a self-proclaimed self-employed person, and Keisuke Koike (24), whose occupation is unknown, both of unknown addresses.
According to the police, last month, he is suspected of defrauding 2 million yen in cash by calling the home of a woman in her 70s living in Yoshikawa City, Saitama Prefecture, pretending to be her son, saying, "I got my adulterous partner pregnant, and I need settlement money."
It means that they remain silent about the investigation.
After receiving a report from a guest of a hotel in Kashiwa City, Chiba Prefecture, that they heard what sounded like a fraudulent phone call from their room, the police investigated and found that the two were based in a hotel room.
A list of names and phone numbers of 300,2 people living in seven prefectures in the Kanto and Kyushu regions was found in the confiscated smartphones, and the police are investigating the repeated fraudulent calls based on these lists.
