 In early October 2011, according to the complaint, Arbabsiar made phone calls at the direction of law enforcement agents to Shakuri in Iran that were secretly monitored.During these phone calls, Shakuri confirmed that Arbabsiar should move forward with the plot to murder the Ambassador and that he should accomplish the task as quickly as possible, stating on 5 October 2011, "just do it quickly, it's late..." Investigations by the FBI disclosed that money had been wired from a Quds Force bank account, and that Arbabsiar correctly identified a known Quds Force officer from a photo array shown to him in custody.On 24 October 2011, Arbabsiar at first pleaded not guilty, but later changed his plea to guilty.
