Finnish police raided an apartment in the southwestern city of Turku on Friday evening and said it was "quite certain" it had identified the attacker who killed two people and wounded eight during a stabbing rampage earlier in the day, local media reported.

The raid occurred just before 10 p.m. after police located a suspected vehicle, a white Fiat Ducato, whose owner lived in a building located in eastern Turku's Varissuo suburb, Finnish newspaper Ilta-Sanomat reported.

A number of people were arrested during the night as the Nordic country investigated their possible link to the attacker of a now "quite certain identity," Finnish news agency SST said.
