Two Russian-Canadian citizens were accused in the United States of sending millions of dollars worth of semiconductors, integrated circuits, and other dual-use electronic devices to Russia through front companies in Brooklyn.

U.S. authorities said Nikolai Goltsiv (37 years old) and Kristina Puzyreva (32 years old) from Montreal were arrested at a Manhattan hotel on Tuesday morning.

Slimdzon Nasrdinov, 52 years old, a resident of Brooklyn with dual Russian and Tajik citizenship, was also arrested, according to a press release from the U.S. Attorney's Office.

The suspects are alleged to have exported over 300 shipments of prohibited materials valued at about 10 million U.S. dollars to Russia over the course of a year, to evade U.S. sanctions imposed on Russian entities and companies linked to the Russian military, according to the statement.

The two companies registered in Brooklyn, through which the shipments were allegedly facilitated, are SH Brothers Inc and SN Electronics Inc

In the same context, U.S. authorities said Goltsiv received orders from Russian end-users in the defense and technology sectors who sought to obtain certain items or parts from the United States.

The authorities added that Goltsiv communicated with American manufacturers and distributors using aliases such as "Nick Stevens" or "Geo Ross".

Goltsiv and Nasrdinov are also alleged to have purchased electronic parts from Brooklyn-based American manufacturers and arranged to send the items to various locations in Brooklyn before illegally shipping the items to different countries such as Turkey, Hong Kong, China, and the United Arab Emirates, with the statement indicating they were then redirected to Russia.

Puzyreva is alleged to have operated multiple bank accounts and financial transactions for the shipments.

Authorities also said the defendants were aware that the exported electronic devices had potential military applications due to a series of exchanged messages between Goltsiv and Nasrdinov from November 2022 to February 2023.

The U.S. Department of Commerce described the contents shipped by SH Brothers Inc as "raising significant concern given their critical role in the production of advanced precision-guided Russian weapons systems, Russia's lack of local production, and the limited global manufacturers," according to the statement.

Authorities said some of the electronic parts and integrated circuits shipped include the Torn-MDM wireless reconnaissance complex, the RB-301B “Borisoglebsk-2” electronic warfare complex, the light multi-purpose guided missile Izdeliye 305E, and the Vitebsk L370 portable air defense missile system.
