Robert A. “Bob” Levinson (born March 10, 1948) is an American private detective and former FBI agent. He disappeared in March 2007 when visiting Iran's Kish Island while apparently researching a cigarette-smuggling case. He had previously worked on an inquiry into the murder of American Paul Klebnikov in Moscow.
The Iranian government has stated that it has no information about the case, but officials from the U.S. State Department have cast doubt on the Iranian government's claims.
On September 5, 2007 Iran blocked a US request to allow Swiss diplomats to go to Kish Island to look for the luggage or other traces of Levinson.
