A Saudi diplomat involved in a fatal road accident while allegedly driving under the influence of alcohol has left Iran, media reported Wednesday.
"The diplomat left Tehran on September 27 after the end of an examination of his case," the official IRNA news agency quoted an "informed source" as saying, without giving further details.
An Iranian citizen was killed mid-March when the Saudi diplomat's car reportedly hit another vehicle on a expressway in Tehran while speeding at 130 kph (80 mph).
Iranian authorities said the accident happened because the diplomat had been driving while drunk and barred him from leaving the country pending "clarification of the (legal) status".
Consumption of alcohol is forbidden in Iran under its Islamic sharia law.
Diplomatic relations between Iran and Saudi Arabia have deteriorated in recent years over their opposing positions on Syria and Bahrain.
Iran's new president Hassan Rouhani has said Tehran is keen to improve ties with Saudi Arabi.
