Swedish security police have detained a man suspected of plotting "devastation endangering the public" in a case linked to violent right-wing extremism.
The man, who had previously been arrested in absentia, is suspected of preparing the crime between August 2020 and this month, prosecutors said.
Police and the prosecution authority gave no more details about the suspected plot in their statements on Friday.
"One person has been arrested on suspicion of preparing for devastation endangering the public," police said.
"The security police have for some time been working with intelligence in the case which is suspected to have links to violent right-wing extremism."
The man is due to appear before judges on Saturday.
