The number of arrests made over a break-in resulting in the murder of a woman in Tochigi Prefecture rose to six after a couple in their 20s — thought to be the masterminds behind the crime — were arrested on Sunday, as four high school boys continue to be held and law enforcement officers search for more details on the incident.
On Thursday morning, four 16-year-olds broke into the house of Eiko Tomiyama, 69, in the town of Kaminokawa, Tochigi Prefecture, to steal valuables.
Tomiyama was stabbed to death, and two of her sons who came to her aid were injured after being attacked with a crowbar.
The four high school boys, who are all from Kanagawa Prefecture, were arrested between Thursday and Saturday.
They are thought to have arrived at the house in Tochigi Prefecture in a luxury foreign car that one of the boys had driven, though they are all under the legal driving age of 18.
