KNOXVILLE, Tenn. (AP) — Prosecutors say an former Tennessee Valley Authority vice president has been indicted for sending more than half a million dollars to Iran for financial investment purposes, which is barred under U.S. economic sanctions against Iran.

Federal agents arrested 57-year-old Masoud Bajestani (BAH-jes-tah-nee) as he arrived at the airport in Atlanta on Sunday. The U.S. Attorney’s Office in Knoxville said on Tuesday that a federal grand jury in December indicted Bajestani for violating the International Emergency Economic Powers Act and making false statements to the TVA.
