At around 10:40 p.m., a can exploded outside the home of an organized crime member in Kamisukiawara City. No injuries or damage to structures were reported.
Police are attempting to confirm that the incident is connected to a gangland war, which has included a number of shooting incidents and possibly one suicide, between the Yamanashi-ikka, an affiliate gang to the Inagawa-kai, and the Yamanashi Kyoyu-kai organized crime group.
The dispute dates back to last November, when an upper member of the Yamanashi Kyoyu-kai was seriously injured after being shot in the riverbed of the Arakawa River.
According to officers from the Minami Kofu Police Station, the discharging of a gun was heard in approximately the same location as the explosion of the can at the end of March.
