Tokyo - A recent knife attack in Japan prompted a 76-year-old former top bureaucrat to murder his own son because he was deeply concerned that he could also inflict harm on others, local media reported on Monday.
Hideaki Kumazawa, who served as a top bureaucrat in the farm ministry, was arrested on Saturday for stabbing his 44-year-old son Eiichiro to death at their home in Tokyo, Kyodo News agency reported.
Kumazawa, who was also Japan's ambassador to the Czech Republic between 2005 and 2008, told police that he was motivated by his son's social withdrawal and domestic violence, Kyodo reported.
Kumazawa said his son "tended to be withdrawn from social life and showed violent behaviour" toward him and his wife, Kyodo reported, citing unnamed investigative sources.
The incident came less than a week after a knife-wielding man attacked two adults and 18 children at a school bus stop in the city of Kawasaki near Tokyo, leaving two people dead and one woman and 17 schoolgirls injured.
