UPI is reporting, using the New York Daily News as a source, that John Walker Lindh was the key to Buffalo Six arrests:

"A "concerned Yemenite" from Lackawanna sent a letter to the FBI in June 2001 that said eight U.S. citizens of Yemeni descent from the upstate, N.Y. city had gone to the Osama bin Laden's al Farooq terrorist training camp in Afghanistan, The Daily News said."

"The FBI investigated but the men denied going to Afghanistan and said they had gone to Pakistan to learn more about Islam and in the summer of 2001, the investigation was at a standstill."

"Lindh began cooperating with investigators on July 15, 2002 and although he could not identify the Lackawanna men because he arrived just as they left, the source told The News he remembered some in the Afghan camp talked about a group from the Buffalo area."

"With this information, the FBI confronted one of the suspects, Mukhtar Al-Bakri, in Bahrain on Sept. 11 and he admitted that the group had attended al Farooq."
