Swedish police said on Friday the masked man who killed a teacher and a boy, and wounded two others in a Swedish school committed the crime racist motives.
The attack that shocked Swedish people was committed by an assailant who walked through a school and stabbed the students and the staff.
The incident took place in Trollhattan, an industrial town of about 50,000 population in the west of Sweden and inhabits a large number of immigrants.
The police reported that the suspect, who was shot and later died of his injuries at a local hospital, had no other criminal record.
Police chief Niclas Hallgren told Swedish public service radio, “"We are convinced that the assailant was driven by racist motives when he carried out the act," and added "We have reached this conclusion based on what we found when we searched his apartment and his behaviour during the act, and also on the basis of how he selected his victims."
