On 6 June 1978, General Nematollah Nassiri was relieved of his post as head of the SAVAK and appointed ambassador to Pakistan.
His place was taken by Lieutenant General Nasser Mogadam, who for many years headed the “Department III” SAVAK.

With the constant development of the Iranian Revolution, the Shah ordered the dissolution of SAVAK and Nassiri was called back from Pakistan.
He was arrested together with 60 other former officials on 7 or 8 November 1978, including high-ranking officials, such as former director of SAVAK Hassan Pakravan and former Prime Minister Amir-Abbas Hoveyda.
When the Shah left Iran on 16 January 1979, Nassiri remained in prison until the fall of Shapour Bakhtiar's government on 11 February.

On 15 February, Nassiri was arrested by revolutionists and brought to the Refah School with other officials.
He was tried in a Revolutionary Tribunal along with 24 other individuals for a total of 10 hours and was charged – without any defence or concrete evidence of guilt – with corruption on earth, massacre of people, torture, and treason.
He was sentenced to death and confiscation of property at 10 p.m. and after the sentence was confirmed by Ayatollah Khomeini, he was executed by firing squad at 11:45 p.m.
