Seven people died and 10 others were injured after a man hit pedestrians with a truck and then stabbed passersby Sunday in broad daylight on a street in Tokyo's busy Akihabara district.

Police arrested the man, Tomohiro Kato from Susono, Shizuoka Prefecture, on the street and seized a survival knife he was carrying. The 25-year-old temp staffer at an auto component factory in the prefecture admitted to stabbing people with the knife, which had a 13-cm blade, from around 12:30 p.m., the police said.

"I came to Akihabara to kill people," investigative sources quoted Kato as telling the police. "I am tired of the world. Anyone was OK. I came alone."
