The British Council said an Iranian employee arrested in Tehran has been acquitted by a court and has returned to the UK.

Aras Amiri was sentenced to 10 years in prison in 2019 on widely criticized espionage charges.

The British Council said on Wednesday that the appeal by its lawyers to the Iranian Supreme Court was successful.

She worked for the consultancy office in London.

“We have always refuted the original charges against Aras,” the council said in a statement.

“We are very proud of his work in our London office as artistic program manager for a better understanding and appreciation of Iranian culture in the UK.”

Iranian officials did not immediately recognize his release.
