Tokyo ? A man plowed into shoppers with a truck Sunday and then stabbed 17 people within minutes, killing at least seven of them in a grisly attack that shocked a country known for its low crime rate.

The lunchtime violence in the Akihabara district, a popular electronics and video game area, sent thousands of people fleeing.

The assault, which occurred on the seventh anniversary of a mass stabbing at a Japanese elementary school, was the latest in a series of knife attacks that have stoked fears of rising violent crime in Japan.

A 25-year-old man, Tomohiro Kato, was arrested with blood on his face.

“The suspect told police that he came to Akihabara to kill people,” said Jiro Akaogi, a spokesman for the Tokyo Metropolitan Police Department. “He said he was tired of life. He said he was sick of everything.”

The violence began when the man crashed a rented, two-ton truck into pedestrians. He then jumped out and began stabbing the people he had knocked down with the truck before turning on horrified onlookers, police said.
