35-year-old Ivan Sechin, the only son of Rosneft head Igor Sechin, died.

Axar.az informs that Russian Telegram channels reported on this.

"The official cause of death is thrombus. Ivan died in the mansion in Krasnogorsk. The security service called an ambulance but gave an inaccurate address. As a result, the doctors were delayed for almost two hours, during which time he died," the report said.

According to the allegations, Igor Sechin forbade the Russian Investigative Committee, the FTX and other security forces to deal with issues related to Ivan's death.

Since 2014, Kich Sechin worked as a manager at "Rosneft".
