ABC News reports investigators have tied the man to a terrorist cell set to
carry out a series of bombings and assassinations in London.
The man, a naturalized citizen from Pakistan, was secretly taken into custody
in April.
He is being held at the Metropolitan Correctional Center in Lower Manhattan
and is said to be cooperating offering investigators significant information
about Al Qaeda's plans.
He is being held as a material witness and his family is now under federal
protection.
The man has told investigators that Al
Qaeda is planning more attacks in the United States. He has also revealed a
scheme to smuggle terrorists across the Mexican border.
The suspect's assertions were part of the intelligence that led to recent
warnings about a summer threat from Al Qaeda.
Another man being held today is kidnapped American Paul Johnson.
A video on an Arabic website shows Johnson blindfolded.
His abductors claim to be with a group called "Al Qaeda In The Arabian
Peninsula." They say they'll kill Johnson unless Saudi authorities free Al Qaeda
prisoners by Friday.
Johnson was taken hostage last Saturday. He has worked in the kingdom since
1992 for defense contractor Lockheed Martin. His son is now trying direct
appeals to the kidnappers.
Paul Johnson III, Son: "Whoever's responsible for this, I would trade in a
heartbeat for my father. He doesn't deserve this and I plead with y'all to
please let my father go."
Johnson's abduction is part of a growing campaign to kill and kidnap
Americans, pushing them out of the Saudi Arabia. The royal family vows to pursue
anti-western militants more aggressively than ever before.
