DeLeo’s bill would prohibit the establishments by making it a crime to conduct or promote a sweepstakes with an electronic machine. Offenders would be fined up to $250,000 per machine or could spend up to 15 years in state prison.
“Owners of these establishments are taking advantage of their patrons and scamming them out of money,’’ DeLeo said in a statement. “This is unacceptable, and I look forward to seeing this legislation passed into law.’’
Attorney General Martha Coakley, who has spent several months trying to stop the cafes from proliferating, praised DeLeo’s efforts.
“These cybercafes are really cyber scams with no posted odds, minimum odds, or guarantee of payouts for patrons,’’ she said in a statement. “This bill makes certain that companies cannot skirt our laws.’’
The legislation exempts the state lottery, as well as betting on horse races, bingo, and charitable gambling events.
While DeLeo is attempting to ban the cybercafes, he is also working behind the scenes with Senate President Therese Murray and Governor Deval Patrick on legislation to legalize casino gambling in Massachusetts.
DeLeo, whose district includes Suffolk Downs in East Boston, has emphasized that he also wants the legislation to permit slot parlors at horse tracks, saying they would provide an economic lifeline for the struggling horse-racing industry.
The Legislature plans to debate gambling bills in September, after Labor Day.
