“SECURITY ALERT: Kindly note there is a new technique used by robbers and carjackers to escape from arrest due to their criminal activities. They are collecting used mobile phone airtime 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 use the scratch card serial numbers to track the phone number it was loaded on. Police is holding two people who fell victim of the trick.
TO BE ON THE SAFE SIDE – Once you load airtime make sure you destroy the card before you dispose it to avoid such incidences. PLEASE SHARE THIS WITH EVERYONE, IT SAVES. Consumer Responsibility – Take Action and Do not become a Victim.”
