The man reportedly asked to speak to the Iranian embassy to deliver a message to the French government, Reuters reports.
A gunman who took two people hostage in central Paris on Tuesday has been arrested and his victims freed "safe and sound", police in the French capital said.
Shocking photos show police decked out in body armour with a local reporter warning of "an armed man". A Paris police official told CBS News there was no immediate indication of a link to terrorism, however members of the force's elite serious crime unit, known as the BRI, were on the scene. The attacker, who appeared to be brandishing a fake weapon, had doused his remaining two hostages in petrol, the source said.
Police have not confirmed that the hostage-taker is armed.
Police also did not confirm reports that one of the hostages was injured.
The area was evacuated and the street, rue des Petites Ecuries, was cordoned off. Negotiations were in progress. "His demands were really vague and incoherent", said an interior ministry official.
