Nazanin Zaghari-Ratcliffe faces a new charge, according to Iranian state media.
The British-Iranian dual national was released from prison in March amid the coronavirus outbreak, but has been wearing an ankle tag that only allows her within 300m (984ft) of her parent’s home in Tehran.
The local TV report cited an unnamed official who said she appeared before a branch of Iran‘s Revolutionary Court in the country’s capital on Tuesday morning.
The 42-year-old, from Hampstead, north London, was granted temporary release during Iran’s COVID-19 lockdown after serving almost all of her five-year sentence.
She was arrested during a holiday with her young daughter Gabriella in April 2016 and accused of spying on the Iranian regime.
Her husband Richard Ratcliffe has campaigned tirelessly for her release.
Ms Zaghari-Ratcliffe’s family suggested recently that her detention could be linked to Iran’s negotiations with the British government over a £400m settlement held by London – a payment the late Iranian Shah Mohammad Reza Pahlavi made for Chieftain tanks that were never delivered.
Tehran has denied that her imprisonment is anything to do with the negotiations.
