On March 16, Satoshi Endo, the 52-year-old boss of the Nagoya-based Kodo-kai, an affiliate group of the Yamaguchi-gumi, and three other suspects are alleged to have beat the worker, 23, in the head and face over an eight-hour period inside an office of the gang in Hachioji City. Injuries to the victim required one month to heal.
Endo has reportedly denied the allegations, telling police that the accusations are not factual.
According to police, the crimes were committed in an attempt to collect the principle of a 3.2-million-yen loan taken out by the victim.
On Monday morning, investigators raided the Nagoya headquarters of the gang in search of evidence connected to the incident.
