Detective Inspector Petri Savela says that Oulu Police are searching for a man who is about 180 centimetres tall, dark-skinned and wearing dark clothes.
After allegedly killing two men at a pub, the man headed toward the Rusko area via the Valtatie bicycle lane.
Police have not yet said whether the perpetrator knew the victims. Police are asking residents of Tuira to stay indoors and others to stay away from the area.
The killings apparently took place outside the Tuisku Pub shortly before 6 pm Wednesday. The suspect remained at large more than three hours later.
