Iran's Police Chief says the mysterious death of Neda Aqa-Soltan, who became a symbol of post-election street rallies in Iran, was a 'prearranged scenario'.

Neda, 26, was shot dead on June 20 in an alley away from the scene of clashes between security forces and demonstrators in Tehran.

She immediately became an international icon after graphic videos of her death grabbed the attention of world media outlets.

Esmaeil Ahmadi-Moqadam, commander of the Iranian Police, said Wednesday that the unfortunate incident - which has been hyped and dramatized by Western media outlets - was in fact a 'premeditated act of murder'.

The Iranian police chief said Arash Hejazi, a doctor who claims he tried to save Neda's life in her final moments, has fanned the flames of the western media hype.

Ahmadi-Moqadam said the Iranian Intelligence Ministry is making every effort to discover the whereabouts of Hejazi. "He has fled the country and is working against the Iranian government abroad."

Media outlets in the West have blamed Neda's death on Iranian security forces, but new revelations have found that she was murdered by a small caliber pistol - a weapon that is not used by Iranian security forces.

The man who drove Neda to hospital said in an interview that her death looked 'highly suspicious', as there were no security forces or Basij members nearby.

The Iranian government is making every effort to identify the culprit behind Neda's death with Iranian President Mahmoud Ahmadinejad demanding a thorough investigation into the incident.

"Amid vast propaganda by foreign media and much other evidence about the heartfelt event, it seems definite that opponents of the Iranian nation interfered (in Iran's internal affairs) for their political misuse," said Ahmadinejad in a letter to Iran's Judiciary chief Ayatollah Mahmoud Hashemi-Shahroudi.
