HELSINKI (AP) — Finnish police say they believe a man who killed a woman and wounded nine others while wielding a sword and a firearm inside a classroom acted alone.

Chief investigator Olli Toyras of the National Bureau of Investigation says the man, who wasn't officially named, is suspected of murder and several murder attempts. No motive or reason for the attack was immediately known.

Toyras said Wednesday that police fired twice to stop the man, a Finnish national born in 1994, after he refused to obey a police order. The suspect, who was seriously wounded, is in custody at a hospital.

Toyras said the man was a student at the Savo Vocational College, which occupies the second floor of the Herman shopping center in Kuopio, central Finland where Tuesday's violence took place.
