Probe nets bomb-making material

LONDON, Aug. 18 (UPI) -- British investigators into the alleged terrorist plot to blow up transatlantic airliners have found a suitcase loaded with bomb-making material.

The discovery was made during a search in Buckinghamshire, the Independent reported. Scotland Yard declined comment but the BBC quoted a police source as saying the suitcase contained "everything you would need to make an improvised device."

Twenty-three men and women were being questioned over the alleged airliner plot and previous terror attacks. No direct links have yet been uncovered between the airline plot and the terrorist attacks on London subways but security and police sources say it is only a matter of time.

In a separate inquiry, a 47-year-old man and a 44-year-old woman were arrested at Holyhead port, on the Isle of Anglesey in north Wales, in an anti-terror investigation. It was not linked to the alleged airliner plot, police said.
