Reported Mass. Lottery Manipulation To Be Probed

State Treasurer Steven Grossman has asked for a review of the Massachusetts Lottery's Cash WinFall game to find out how a single group of bettors was able to manipulate a multimillion-dollar drawing and win nearly all of the prize money.

Grossman, whose office oversees the lottery, told The Boston Globe that while there is no presumption of wrongdoing, he wants to make sure the integrity of the lottery is protected. He requested that state Inspector General Gregory Sullivan conduct the probe and Sullivan agreed.

The Globe reported on Sunday that a betting group led by an MIT graduate was able to buy up more than 80 percent of the tickets for an August 2010 Cash WinFall drawing and walk off with most of the more than $2 million in prize money.
