ST. PETERSBURG, August 24 (RAPSI, Mikhail Telekhov) - The Dzerzhinsky District Court of St. Petersburg has extended detention of the director of the North-West department of the nuclear supervision agency Rostekhnadzor Grigory Slabikov charged with complicity in embezzlement of 4.7 billion rubles ($70 million at the current exchange rate), the United press service of St. Petersburg courts has told RAPSI.

Slabikov will stay jailed until December 11. His daughter Yelena involved in the case has been released from detention and placed under house arrest for the same term.

The defendants have pleaded guilty, the statement reads. Moreover, they have told investigators where another stolen 500 million rubles were hidden.

Investigation into embezzlement of 4.7 billion rubles from compensation funds of the Union of engineering companies Standard-Project, the Union of locating engineers Standard- Front-end Engineering and the Union of construction organizations Construction Power began in 2017.

According to investigators, Slabikova was an intermediary between gang members, who were stealing money from compensation funds of three self-regulatory organizations in St. Petersburg, and her father, who is believed to be a coordinator in the crime.

Slabikov stands charged with assistance in adding companies controlled by gang members to the register of self-regulatory organizations without inspections. He allegedly received around 1 million rubles for each operation. He was put in detention on May 11.

Last October, three other persons were detained as part of the case, and one more defendant was placed under house arrest.
