McALLEN, Texas (AP) — Two South Texas school board members and another man have been indicted in a public corruption case linked to educational services.

An indictment unsealed Friday in McAllen names 53-year-old Eloy Infante and 45-year-old Elpidio Yanez Jr., plus 50-year-old Adrian Guerrero.

Federal prosecutors say the men from Donna are charged with conspiracy, attempted extortion and federal programs bribery.

The suspects allegedly attempted to extort bribes from another person whose company provided services to the Donna Independent School District.

The Oct. 27 indictment says the businessman was told he must pay $10,000 each to Infante and Yanez to retain district contracts. Guerrero alleged served as the middleman.

Prosecutors didn't immediately provide custody information on the suspects or attorneys for them. Messages left for Infante and Yanez weren't immediately returned Friday.
