I heard many people asking how and why would drug cartel plant drugs in the lady's bag, some also asked assuming it's tru e they plants it in her bag then his are they going to retrieve it at he destination airport while. There are a lot of things that I you weren't following the saga from onset they wouldn't make sense at all..Here is a brief ordeal of how it happened and answers to some questions above.

1. The airport cartel claimed that some one brought the luggage to help them send over to Saudi Arabia, its an illegal thing they does, they will collect luggage from unknown person and add it to soomeones luggage and send across, the person at the receievng end is aware of the parcel and will pick it at the airport once the luggage arrives.
2. In the case of Zainab Aliyu same thing happened, they registered a bag containing 2000 units of tramadol on her name, she has a small luggage which her total weight required is not IP to required KG so they used the opportunity to add the additional bag to her luggage and register it with her name, at the destination she only picked her bag which she was aware of and left the other behind since she wasn't aware that it do exist, Saudi official while carrying out scan of luggage later discovered that bad that were left perhaps the person who is supposed to pick the bag at the destination did not arrive on time and the bag was left behind which the Saudi agents intercepted, the bag was labelled with Zainab's name so they traced her to her hotel and arrested her.
3. The case was a bit straight forward as the item was in a luggage she was not aware of not in her main luggage. Immediately her parent realized what happened they went to the airport and demand for investigation on the luggage added to her, when the official that worked that day were intorregated they indeed confessed that they added that bag to her and many other passengers, its a normal thing they do there, add luggage to a passenger and collect money for it, the owner will received the added luggage at the destination. On searching through their phone they discovered WhatsApp chat where one of the official snapped the added bag and sent to some one at Saudi who will pick it.

I have to write this price to clear air on some of the questions that are not very clear, its a clear case of framing there was nothing like conspiracy or making some people as scapegoat to save the innocent lady.
