The former mayor of a North Texas town is accused of soliciting a $70,000 bribe to push for a deal that benefitted a real estate broker.

The U.S. Attorney's office in Sherman on Thursday announced the indictment of David Dorman. Dorman was mayor of Melissa — 30 miles northeast of Dallas — for 10 years.

A federal indictment accuses Dorman of extortion. Authorities say Dorman pushed to annex 33 acres of land from neighboring McKinney so that it could be improved with water and sewer lines. They accuse real estate broker John Christie of paying Dorman three checks totaling $30,000 in 2007.

Dorman lost his re-election bid in 2009.

Attorney Barry Sorrels says Dorman will plead not guilty and fight the charge.

Christie's attorney did not return a message.
