Japanese police have raided the home of a man suspected of slashing schoolgirls and others in a deadly knife attack this week that ended with him killing himself.

The attack near Tokyo on Tuesday has raised concerns about how children can be protected on their way to school.

Officials say the knife-brandishing man ran while slashing a group of schoolgirls and their parents walking to or waiting at a bus stop in Kawasaki, killing an 11-year-old girl and a 39-year-old man before fatally slashing himself. At least 17 people were injured.

On Wednesday, police raided the home of the alleged attacker, 51-year-old Ryuichi Iwasaki, in another part of Kawasaki.

Prime Minister Shinzo Abe urged security officials to increase safety measures to protect commuting schoolchildren.
