JHB "Security"
Put mine in my checked bag, together with a 15mm spanner and a cycle tool with various heads to assemble my bike at the other end; x-ray obviously spotted this stuff, informed "Security" who promptly raided my bag (in the interests of security of course!) as it waited for loading, and relieved me of all the above-mentioned hardware.........highly inconvenient, and the airline only pays out on 'weight lost', not value of stolen goods.........
No problem the next time, shrink-wrapped the bag, stymied the b*stards. Take the advice.
