Two Yemeni men are detained after guards see them taking photos at 26 Federal Plaza in New York City. They are questioned by INS agents and let go. A few days later, their confiscated film is developed, showing photos of security checkpoints, police posts, and surveillance cameras of federal buildings, including the FBI’s counterterrorism office. The two men are later interviewed by the FBI and determined not to be a threat. However, they had taken the pictures on behalf of a third person said to be living in Indiana. By the time the FBI looks for him, he has fled the country and his documentation is found to be based on a false alias. In 2004, the identity of the third man reportedly still will be unknown. The famous briefing given to President George W. Bush on August 6, 2001 (see August 6, 2001), will mention the incident, warning that the FBI is investigating “suspicious activity in this country consistent with the preparations for hijackings or other types of attacks, including recent surveillance of federal buildings in New York.” When Bush’s August 6 briefing will be released in 2004, a White House fact sheet will fail to mention the still missing third man.

Issa al-Hindi or Issa al-Britani), an alleged al-Qaeda operative in British custody, was sent to the US in early 2001 by Khalid Shaikh Mohammed to case potential targets in New York City. He headed a three-man team that surveyed the New York Stock Exchange and other buildings. While there are obvious similarities between the two Yemeni man with an unknown boss and Barot with two helpers, it is not known if the two cases are related. [New York Times, 8/7/2004]
