According to a press release, the house search was also carried out in several places in Norrköping with the help of, among other things, the police bomb protection. The person is 28 years old and is on probable cause, the higher degree of suspicion, for a violation of the Flammable and Explosive Goods Act.

"Can be linked to multiple crimes"

- After investigation the person can be linked to several crimes and therefore this effort has now been carried out. At present, we cannot go into crime locations and crime times any more closely. Now the investigation is continuing and we will provide more information when possible, says Chamber Prosecutor Karin Sandén.

Prosecutor Karin Sandén is also holding investigations into the explosion in Hageby in January and the double murder outside a nightclub in central Norrköping last fall. It is unclear if this arrest has links to them.
