On April 25, 1991 he was assigned by the intelligence commander of the Revolutionary Guards and representative of supreme leader in Malayer and other government authorities to infiltrate into the NLA. As a lieutenant in the army he requested to join the NLA several months after failed attacks by the Guards Corps against the NLA forces along Iran-Iraq border region. His mission was to carry out a suicide attack against the leadership of the Mojahedin which failed and he was arrested by the NLA’s counter Intelligence.
He was detained for three months and then expelled from the NLA to go after normal life, but he insisted on remaining with the Mojahedin. In a letter in which he admitted to his mission he wrote: "I was assigned by Ali-Mohammad Panji from the Revolutionary Guards Corps on April 25, 1991. In the meeting where I was assigned, Gholam Akbari, head of the intelligence, Manouchehr Abedi, supreme leader’s representative in Malayer, Ali Fazelian, Friday prayers leader at the time, Mansour Omid, Revolutionary Guards Corps deputy and Reza Esmail-Pour, in charge of the Guards Corps supply in extraterritorial operations were present. My assignment was to carry out a suicide attack against the leadership of the People’s Mojahedin Organization using hand grenade or TNT which had to be prepared locally… to avoid any leakage of information on the mission I was supposed to go for it on my own and plan for necessary supplies and the operation on the scene. The location for operation had to be in a general meeting."
On April 17, 2001, Sadeqi Nejad received a coded letter together with a message from his wife from Iran. The purpose of the letter was to call him back to the headquarters to see why the mission was not carried out. Upon the receipt of the message he planned his escape to Iran and in June 2002 he stole a vehicle, some money and equipment and ran (with a car?) to Iran through the Jalawla region, 30 km from the Iranian border.
