New York's attorney general has started investigating the fantasy sports companies DraftKings and FanDuel after reports that an employee may have used inside information to win $350,000 in a football contest.

Eric Schneiderman sent letters to the two big players in fantasy sports, saying that the allegations raised legal questions about the fairness, transparency and security of the companies, according to copies of the letters provided by his office.
