The police said they are also trying to build a murder charge against Hisato Obayashi, a former member of a gang linked to Japan's largest crime syndicate, the Yamaguchi-gumi, for allegedly fatally shooting another police officer, Kazuho Hayashi, 23, during the incident in the town of Nagakute.

Obayashi has denied he intended to murder anybody, according to the police.

He is suspected of shooting his 25-year-old son, Kento, and 21-year-old daughter, Risa, at his home after they called the police when he became violent following arguments with his former wife, Michiko Mori, 50.

"I asked her to come back to me but she refused. That made me angry and I shot my son and others," the police quoted Obayashi as telling them.
