This is most probably what caused the death of Litvinenko:
Litvinenko claimed this display of affection was the first public sign of a secret that had long been known by some within the KGB. He said Putin had been denied a place in the foreign intelligence division as a young recruit “because, shortly before his graduation, his bosses learned that Putin was a pedophile.”
“Many years later, when Putin became the FSB director and was preparing for the presidency, he began to seek and destroy any compromising materials,” Litvinenko wrote. “Among other things, Putin found videotapes in the FSB Internal Security directorate, which showed him making sex with some underage boys.”
