Sept. 26, 2000 -- He is under threat — in such danger that he is believed to have been placed in the United States witness protection program.

He’s been called the $4 million mystery man — a reference to the U.S. government’s reward money he will possibly collect for his information.

He is also considered the pivotal witness in the Lockerbie bombing trial and it looks like he is finally going to testify.

The former Libyan double agent — Abdul Majid Giaka — looks set to testify today at the Lockerbie bombing trial at Camp Zeist in the Netherlands after new U.S. intelligence documents were released to the court.

The trial has been deadlocked for weeks by defense claims that the CIA had not handed over all its material on Giaka.

Giaka became a U.S. double agent shortly before the 1988 bombing.

The New York-bound Pan Am flight 103 exploded over Lockerbie, Scotland, on Dec. 21, 1988, killing 270 people.

The trial is being held under Scottish law in the Netherlands.

CIA Hands Over New Cables

Last week, the spy agency handed over some 36 new intelligence cables. The defense teams wanted even more, but the Scottish judges ruling on the case rejected their requests.

Now the prosecution’s star witness can take the stand when the hearing resumes.

“We certainly expect Giaka to be here on Tuesday morning,” said chief prosecutor Lord Advocate Colin Boyd.

Giaka is a former Libyan secret agent who also worked for U.S. intelligence.

He, and the intelligence cables, are central to the prosecution’s claim that two Libyans, Al-Amin Khalifa Fahima and Abdel Basset al-Megrahi, blew up Pan Am flight 103 over Lockerbie, Scotland in 1988.

Testifying in a Wig?

Giaka claims he worked with the accused at Malta’s Luqa airport when they planted a suitcase bomb on a plane for Frankfurt. The bomb was eventually transferred to the Pan Am flight bound for New York at London’s Heathrow airport.

Giaka is believed to be the only person who can link the two suspects to the bomb that killed 270 people.

He is said to be so concerned about his safety, that he asked the court if he could testify wearing a wig and heavy stage makeup.

Although the judges refused that request, Giaka will testify from behind a screen with his voice distorted. He has been living under a new identity with government protection since his defection to the U.S. after the bombing.
