The father is said to have flown into a rage after finding a graphic mobile phone video of his best pal Sviridov making the child perform sex acts. In harrowing footage, the sickened dad’s daughter, now nine, was heard pleading: “Oleg, that’s enough, I can’t take it anymore. I want to go home”. The dad was hailed a hero by locals in the village of Pribrezhnoye who even raised funds for his initial legal fees. A petition signed by 2,500 people demanded that he should be fully acquitted. They supported him for “saving our children by ridding us of a child sex attacker”. Sources close to the case said that detailed forensic evidence showed that Matrosov had not stabbed Sviridov in a forest where the dead man’s body was found later in the makeshift grave. There are claims Sviridov was given an ultimatum to go to the police and confess to sexually abusing the girl, or face the father’s wrath.
