DETROIT (AP) — Two Detroit-area businessmen were charged with paying and giving gifts to basketball and football players at the University of Toledo to take part in a point-shaving scheme, according to a federal indictment filed Wednesday.

Six former Toledo players also were accused of taking part in the alleged scheme by either affecting the outcomes in games or giving the two businessmen information so that they could place wagers on the games.

The FBI began investigating point shaving at Toledo four years ago. They said the scheme began in the fall of 2004 and continued until 2006.

Ghazi Manni, 52, of Sterling Heights and Mitchell Karam, 76, of Troy were charged with conspiracy to influence sporting contests by bribery.

The pair bet about $407,000 on Toledo basketball games between November 2005 and December 2006, according to the indictment.

The six players also were charged with conspiracy to influence sporting contests by bribery.

The indictment charges three former football players: Adam Cuomo, 31, Harvey ‘‘Scooter’’ McDougle Jr., 24, and Quinton Broussard, 25. Also charged were former basketball players Keith Triplett, 29, Anton Currie, 25, and Kashif Payne, 24.

Until now, only three former players at the school had been linked to the allegations.

Former basketball player Sammy Villegas was charged last June with shaving points in games during the 2004-05 and 2005-06 seasons.
