Rahmatabadi was shot in the chest and head Sunday night by someone who likely fired at him from inside the vehicle in Sabalan Square in the eastern section of the Iranian capital, police told the semiofficial Fars News Agency.
"Investigations show that two bullets were fired at the victim from inside the car," IRNA quoted a police official as saying. "Since the shells of the two bullets were found in the car, most probably the attacker had been inside the car and talking to Mr. Rahmatabadi."
The official said there was no sign of any struggle at the scene.
Alaeddin Boroujerdi, chairman of the Iranian Parliament's National Security and Foreign Police Commission, said, "We should wait for the police's final report in this connection to see if this murder has been for security reasons or not."
