Nagano Prefectural Police on Sunday arrested a 46-year-old man who is suspected of fatally stabbing one person and injuring two others in front of Nagano Station days earlier.

Yusuke Yaguchi, an unemployed man from the city of Nagano, who had apparently been on the run since Wednesday, was arrested at his home on suspicion of attempted murder. The police said he has remained silent during police questioning. Authorities raided his home in an apartment complex the same day.

It is believed that the suspect did not know the people he attacked. Police are investigating his motive, believing the attack was random.
