An American man who disappeared in Iran more than six years ago had been working for the CIA in what U.S. intelligence officials describe as a rogue operation that led to a major shake-up in the spy agency.

Robert Levinson, a retired FBI agent, traveled to the Iranian island of Kish in March 2007 to investigate corruption at a time when he was discussing the renewal of a CIA contract he had held for several years. He also inquired about getting re­imbursed for the Iran trip by the agency before he departed, according to former and current U.S. intelligence officials.

After he vanished, CIA officials told Congress in closed hearings as well as the FBI that Levinson did not have a current relationship with the agency and played down its ties with him. Agency officials said Levinson did not go to Iran for the CIA.

But months after Levinson’s abduction, e-mails and other documents surfaced that suggested he had gone to Iran at the direction of certain CIA analysts who had no authority to run operations overseas. That revelation prompted a major internal investigation that had wide-ranging repercussions, the officials said, speaking on the condition of anonymity.

The CIA leadership disciplined 10 employees, including three veteran analysts who were forced out of their jobs, the officials said.
