The task force investigating the Olympic bombing and two other Atlanta attacks found bomb components at the home of a man accused of gunning down two police officers.
"It was brought to our attention, and we're looking into it," FBI spokeswoman Celestine Armstead said Tuesday. "That's all we are prepared to say at this time."
Federal and state bomb investigators were called in Monday after Atlanta police arrested Gregory Paul Lawler, 45, on charges of murder and aggravated assault in the fatal shooting of Officer John Sowa, 28, and the wounding of Officer Patricia Cocciolone, 35.
But Lawler's attorney said his client had nothing to do with the bombings. "They are looking at him because they don't have anyone else to look at," said Michael Hauptman.
The task force said it seized the explosive materials from Lawler's apartment along with militia manuals and stockpiled weapons. It was not immediately known what sort of explosive materials and firearms were seized.
