An Iranian blogger who was jailed for insulting the Supreme Leader Ayatollah Ali Khamenei has died, his lawyer said Thursday, according to a report from Agence France Presse.

Omid Mir Sayafi was being held at the Evin prison, and his lawyer, Mohammad Ali Dadkhah, told AFP that while there is no official report on his death, "officials in the prison said that he committed suicide."

Dadkhah demanded "an immediate inquiry and an autopsy into why he died," AFP reported. He said another prisoner, whom he identified as Dr. Hessam Firouzi, "had warned officials in the jail of the state the blogger was in."

He told AFP that Firouzi reported that Sayafi was very depressed.

"Dr. Firouzi called me from the jail to say Omid had a slowed heartbeat and he had taken him to the infirmary, but that doctors there did not take this seriously and said he was faking it," Dadkhah told AFP.

Sayafi was sentenced in February to 30 months in prison for insulting Kahmenei and the late Ayatollah Ruhollah Kohmeini, AFP reported.
