Did you pack this yourself, sir?

Luggage featuring embossed images of a gun, knife or axe is likely to spark alerts at airports, security experts warned yesterday.

The cases, sold online for up to £98, were described as bringing 'a touch of black humour and novelty to an object which is usually rather boring' by retailer kidslovedesign.com.

But aviation security expert Bruce Schneier warned: 'They're not in good taste... It's a funny joke, but remember that there are no jokes when it comes to airport security.'
