On a visit to St. Petersburg, Russia, in 2005, New England Patriots' owner Robert Kraft says he had one of his three Super Bowl rings taken, in broad daylight by Russian president, Vladimir Putin. He said,
"I took out the ring and showed it to (Putin). And he put it on and he goes, 'I can kill someone with this ring,'" Kraft said, according to the New York Post. "I put my hand out and he put it in his pocket, and three KGB guys got around him and walked out."
After the incident he said that he received a call from the White House telling him to say he gave it to Putin as a gift, in order to preserve US Russian relations. In later quotes Kraft does not specifically say that Putin 'stole' the ring, he just said that he had emotional attachments to it as it had his name on it. Currently the ring is on display in the Kremlin and is now the reason of the recent popularity of Patriots fans in Russia.
