Aug. 25 (UPI) -- New evidence caused the trial of a Libyan man charged with building the bomb that brought down Pan Am Flight 103 over Lockerbie, Scotland, to be postponed for a third time in Federal Court in Washington.

U.S. District Court Judge for the District of Columbia Dabney Friedrich postponed the trial of Lybian Abu Agila Mohammad Mas'ud Kheir Al-Marimi Monday, a day before jury selection was set to begin, after his defense team said new evidence had emerged that required investigation on "constitutional and ethical" grounds.

The BBC said it had information that a new date for the trial has been set for January, more than 20 months after Al-Marimi was originally due to stand trial.

The first postponement was due to ill health and then a second start date in April was pushed back after his lawyers requested more time to prepare their defense.
