SBU detained a businessman in Kyiv who supplied building materials (sand, crushed stone, cement) to Russia for constructing fortifications including 'dragon's teeth' pyramidal anti-tank barriers in the temporarily occupied Zaporizhzhia region.

The Security Service of Ukraine (SBU) has detained a businessman in Kyiv who supplied building materials to Russia for the construction of fortified areas in the temporarily occupied territories.

The detainee is the owner of several enterprises from the temporarily captured city of Berdiansk, Zaporizhzhia region.

He supplied Russian companies with sand, crushed stone and cement for the construction of fortifications on the southern front.

The issue concerns the mass production of pyramidal anti-tank reinforced concrete structures, better known as 'dragon's teeth.'

During the search of the detainee's apartment in the Ukrainian capital, law enforcement officers discovered documents and other material evidence of criminal activity in favor of Russia.

The perpetrator was served with a suspicion notice under Part 4 of Article 111-1 of the Criminal Code of Ukraine (conducting economic activities in cooperation with the aggressor state, illegal authorities created in temporarily occupied territories, including by the occupation administration of the aggressor state).

The suspect is in custody.

In April 2024, Portnov transferred ownership of a luxury estate outside Kyiv to his children through a notarized deed of gift.
