Iran has released on bail a local British embassy employee detained three weeks ago on charges of inciting unrest following the country's disputed presidential election.
The lawyer for Hossein Rassam, chief analyst at the British embassy in Tehran, said bail was set at $US100,000.
Mr Rassam was the last employee still in detention of nine Iranian British embassy staff held late last month for alleged involvement in mass street protests following the 12 June election, which defeated pro-reform candidates say was rigged.
Hardline Iranian media have said Mr Rassam played a key role in post-election unrest last month and his arrest shed new light on Britain's "subversive activities". The eight other embassy employees were freed earlier.
Britain has denied Iranian accusations that embassy staff were involved in instigating mass demonstrations over the election.
