The lawyer for an Iranian student activist who died in jail accused top judiciary officials on Sunday of murdering his client.
Lawyer Khalil Bahramian said he filed a lawsuit against judiciary officials for allegedly murdering student activist Akbar Mohammadi.
Mohammadi died in Evin, Iran's most notorious prison, in July after a nine-day hunger strike to protest lack of medical care. He had been jailed for taking part in protests at Teheran University in July 1999 - Iran's biggest anti-government demonstrations since the 1979 Islamic revolution.
Mohammadi was sentenced to death on charges of endangering national security, but his sentence was later reduced to 15 years in prison.
"I filed a lawsuit against Evin prison officials for the deliberate murder of Mohammadi," Bahramian told The Associated Press on Sunday.
But Bahramian said he was immediately summoned to the judiciary for "insulting judiciary officials." He has been asked to appear in court Tuesday to respond to the charges.
"Iranian prison officials have a track record of giving false information about the fate of political prisoners," said Joe Stork, deputy director of the Middle East and North Africa division at Human Rights Watch.
