Westgate: How police used call data trail to arrest terrorists

A senior crime analyst has told a trial court in Nairobi that the suspects held over the September 21, 2013 Westgate terrorist attack communicated on mobile phones with the four attackers killed at the mall.

They communicated throughout the planning and execution of the attack, the analyst who said he sifted through “mountains” of call data records to come to his findings, told the court.
