My concern is that all 15 crew members were held so that must include the cockpit crew as there can only be about 12 in the back. I find it difficult to believe that the flight crew could have been involved
I worked at JNB for 30 years and the baggage pilferage problem, which reached epidemic proportions a year or so ago, is still prevalent. Outgoing bags as well as incoming are at risk. Planting the drugs with possibly one (cabin?)crew member involved is a possibility.
