A potential criminal tried to do his best Crocodile Dundee impression and pull a fast one over police, but they just weren’t buying it.

Officers from the Tasking Team in Greenwich were out and about last night when they decided to stop and search a man.

On him they found a knife (pictured) that he had tried to conceal.

But despite being caught red-handed, he still tried to get away with it.

Not by fleeing the scene. No, he tried to tell officer that in fact it was not a knife, but instead a work tool.

This didn't work and he was promptly arrested.
