I think we will find it is not that simple.
This not a few kgs by a crewmember for some pocket money. 50 kgs in three bags?? Thats a large mass that would easily show up on the scanners at ORT and Heathrow. The drug dogs at Heathrow would pick it up a mile off.
This required a high level of organisation at both ends. The bags would be either anonomosly labelled or labelled with some elses name.
Lots more to come - but will we hear??
