In Sweden, officers of the Swedish Security Service have arrested a person who worked "in a high-technology sector" and is believed by investigators to be a Russian agent.

"This individual is suspected of having been recruited as an agent by a Russian intelligence officer who was working under diplomatic cover in Sweden," Daniel Stenling, the Swedish Security Service Head of Counter-Intelligence, said in a statement.

The Swedish tabloid Dagens Nyheter first reported the spy bust.

From NPR:

The individual, whose name has not been disclosed, was passing information to Russia since 2017, the Swedish Security Service says. He or she was working in a high-technology sector "on tasks known by our Service to be the type of intelligence sought after by foreign powers," the agency said. Swedish police officers working with security service agents arrested the suspect on Tuesday evening, in the midst of a meeting in central Stockholm. (…) Kremlin spokesperson Dmitry Peskov did not comment on the arrest and instead redirected an inquiry to Russia's Foreign Ministry. Its embassy in Sweden has not made public remarks.

Still no comment from Russia, beyond those remarks by Peskov, at noon on Thursday in the United States.

Video footage that appears to show the suspect led out of a restaurant by 'Säpo' (Sakerhetspolisen) officers is circulating on Swedish media, as the BBC reported.

Excerpt from the BBC:

A witness quoted by Swedish newspaper Aftonbladet said several officers of the Swedish security police, known as Sapo, stormed the restaurant and surrounded a table where two people were sitting having a meal. Swedish media said a second person was also detained in the operation but later released after claiming diplomatic immunity.

The Aftonbladet headline? "Another [Russian] Spy has been Arrested."

Here is the Swedish government's news release about the arrest of the suspected Russian agent.
