Christian prisoner Saeed Abedini, who has been receiving hospital treatment for two months, was beaten before he was taken back to prison, his wife says.

Saeed, who is serving an eight-year prison sentence for “setting up house churches in order to disrupt national security”, was returned to Rajaei Shahr Prison in Karaj on Tuesday 20 May.

His wife, Nagmeh, says his mother was also beaten and left in a “bad condition”.

Nagmeh says her husband’s body was left bruised after he was stunned with a taser, and that he was also beaten, leaving him with internal bleeding.

Saeed, who lives in America, was arrested during a visit to his family home in early October 2012.

He was sentenced by Branch 26 of the Islamic Revolutionary Court in February 2013. His appeal was rejected by Branch 36 of the Court of Appeals in Tehran.
