Japanese police recently arrested a group of unlikely criminals, three grandpas in their late sixties, seventies, and eighties accused of breaking into at least two homes and suspected of ten other burglaries.

Hideo Umino, 88, Hidemi Matsuda, 70, and Kenichi Watanabe, 69 allegedly met behind bars and decided to team up after being released in order to commit crimes more efficiently. The trio, dubbed “G3S” by police (homophonous for ‘grandpas’ in Japanese), stand accused of breaking into an empty house in Sapporo, the main city on the island of Hokkaido in May and stealing 200 yen ($1.3) and three bottles of whisky worth about 10,000 yen ($65). the following month, they allegedly robbed another empty house and stole jewelry worth approximately one million yen (US$6,400). Police is currently investigating the group’s involvement in 10 other burglaries in the cities of Sapporo and Ebetsu.
