The Avangard player collapsed on the team bench during his side’s match against Moscow region’s Vityaz in October last year. He died despite efforts by medics at the stadium to revive him.

Doctors were cleared of blame in the initial investigation even though they did not have a working defibrillator, with the primary cause of Cherepanov's death attributed to a heart defect.

But now the prosecutor’s office says it will re-examine why he died. Although they have not said what's prompted a second investigation.
