MADRID, Spain May 7, 2004 — The fingerprints of the American lawyer arrested in Oregon in the Madrid terror bombing probe were found on a bag containing detonators like those used in the March 11 attack, the Spanish government said Friday.
The plastic shopping bag was found inside a stolen van left near the train station from which three of the four bombed trains departed, an Interior Ministry official said on condition of anonymity.
Brandon Mayfield, a 37-year-old lawyer and former U.S. Army officer who converted to Islam, was taken into custody Thursday by FBI agents, who also searched his home in the Portland suburb of Aloha.
It was the first known arrest of a U.S. citizen in connection with the March 11 attack in Madrid that killed 191 people and injured 2,000 others.
The detonators in the bag were of the same kind used in the attacks, the government has said previously.
