The Spanish National Police do not consider the explosion in the city of Oviedo (the autonomous community of Asturias) to be related to terrorism, EFE reported.
According to the media, the alleged perpetrator of the shooting and the owner of the backpack with explosives has a criminal record. The subject's profile rules out a terrorist motive, police sources said.
The ABC newspaper revealed for its part that the police arrested a man who could have fired the shots. The suspect tried to flee the scene in a taxi.
