I got this from a friend in Nairobi but the content/information is helpful to us too but some accident also occurred in Dar, not territory bound!
Kindly remember this technique used by robbers and carjackers to escape from arrest due to their criminal activities. They are collecting used scratch cards and once they abandon the car or where they dump the dead bodies they leave the already used scratch card at the scene. Once the police arrive they are using the scratch card serial numbers to track on which phone number it was loaded then they start tracking the phone number owner. Kindly once you load airtime make sure you destroy the card before you dispose it to avoid such incidences. Share this information with your friends.
