A London lawyer has credited actor Dustin Hoffman with saving his life when he suffered a heart attack while jogging in the city\'s Hyde Park, becoming the latest celebrity in recent weeks to help rescue a person in crisis. Sam Dempster, 27, told Britain\'s Sun newspaper on Tuesday that Hoffman came to his aid when he collapsed in the park 10 days ago, and called emergency services. \"I have no memory of what happened. The paramedics told me I had been saved by Dustin Hoffman. It\'s unbelievable,\" Dempster was quoted as saying. Paramedics told the newspaper that the Rain Man star, 74, called emergency services and tended to Dempster as he waited for them to arrive. Hoffman, who has a home nearby, left only after they had re-started Dempster\'s heart. Hoffman\'s Los Angeles-based representative confirmed the account. Hoffman is the latest celebrity turned Good Samaritan in recent weeks. Grey\'s Anatomy star Patrick Dempsey helped to pry a teenager from a car wreck in Malibu recently, and actor Ryan Gosling grabbed a British woman to stop her from being hit by a car in Manhattan in April.
