Two Iranian nationals were arrested Saturday in a hotel room at the Springfield Hilton as they allegedly delivered $85,000 to an undercover Drug Enforcement Administration agent posing as a heroin and opium dealer, a DEA spokesman said yesterday.

The money was to be a down payment for $430,000 worth of heroin and opium that the two arrested men said they intended to sell in the Washington area, according to Bill Schnepper, a DEA spokesman.

The two arrested men are Nasr Sateri, a 40-year-old naturalized U.S. citizen, of the 3700 block of George Mason Drive in Falls Church; and Mohammad Ghaziaskar, 30, of 7606 Sycamore Drive in Falls Church, Schnepper said.

The two men agreed to buy 4.4 pounds of heroin, worth $400,000, and 1,000 sticks of opium, worth $30,000, from the undercover agents in the joint DEA-FBI investigation, Schnepper said. The agents did not produce any actual heroin or opium in the deal, he said.

The two men were arraigned Saturday in Alexandria before U.S. Magistrate Quin Elson, who set bond for Sateri at $200,000, and for Ghaziaskar at $100,000. Both are still in custody, Schnepper said yesterday.
