Norrköping has been shaken by a series of suspected arson attacks over the past three nights.

Police are investigating four incidents, including two fires early Sunday morning—one at a car dealership and another involving flammable containers on a street.

Earlier fires on Thursday and Friday targeted residential buildings, with police linking these to gang activity.

While no injuries have been reported, the motives remain unclear, and no suspects have been apprehended.

Authorities are working to determine if the incidents are connected.

"We are investigating potential links between these events," said police spokesperson Mats Pettersson.
