According to two separate reports by Dutch newspaper NRC Handelsblad and Swiss newspaper Tages-Anzeiger, the two were apprehended in The Hague in early 2018. The reports also said that the Russians were found in possession of equipment that could be used to compromise computer networks. They are believed to work for the Main Intelligence Directorate, known as GRU, Russia’s foremost military intelligence agency. The apprehension was the result of cooperation between various European intelligence services, reportedly including the Dutch Military Intelligence and Security Organization (MIVD).

The laboratory, located in the western Swiss city of Spiez, has been commissioned by the Netherlands-based Organization for the Prohibition of Chemical Weapons (OPCW) to carry out investigations related to the poisoning of Russian double agent Sergei Skripal and his daughter Yulia in March of this year. It has also carried out probes on the alleged use of chemical weapons by the Russian-backed government of President Bashar al-Assad in Syria. In the case of the Skripals, the laboratory said it was able to duplicate findings made earlier by a British laboratory.

Switzerland’s Federal Intelligence Service (NDB) reportedly confirmed the arrest and subsequent expulsion of the two Russians. The Swiss agency said it “cooperated actively with Dutch and British partners” and thus “contributed to preventing illegal actions against a sensitive Swiss infrastructure”. The office of the Public Prosecutor in the Swiss capital Bern said that the two Russians had been the subject of a criminal investigation that began as early as March 2017. They were allegedly suspected of hacking the computer network of the regional office of the World Anti-Doping Agency in Lausanne. The Spiez laboratory was a target of hacking attempts earlier this year, according to a laboratory spokesperson. “We defended ourselves against that. No data was lost”, the spokesperson stated.

On April 14, Russian Minister of Foreign Affairs Sergei Lavrov stated that he had obtained the confidential Spiez lab report about the Skripal case “from a confidential source”. That report confirmed earlier findings made by a British laboratory. But the OPCW, of which Russia is a member, states that its protocols do not involve dissemination of scientific reports to OPCW member states. Hence, the question is how Foreign Minister Lavrov got hold of the document.

As intelNews reported in March, in the aftermath of the Skripals’ poisoning the Dutch government expelled two employees of the Russian embassy in The Hague. In a letter [.pdf] sent to the Dutch parliament on March 26 —the day when a large number of countries announced punitive measures against Russia— Holland’s foreign and internal affairs ministers stated that they had decided to expel the two Russian diplomats “in close consultation with allies and partners”. The Russians were ordered to leave the Netherlands within two weeks. It is unknown whether the two expelled Russian diplomats are the same two who were apprehended in The Hague, since none have been publicly named.

A November 2017 parliamentary letter from Dutch minister of internal affairs Kajsa Ollongren, states[4] that Russian intelligence officers are “structurally present” in the Netherlands in various sectors of society to covertly collect intelligence. The letter added that, in addition to traditional human intelligence (HUMINT) methods, Russia deploys digital means to influence decision-making processes and public opinion in Holland.
