Prize draw.

Offering cash rewards to grasses of benefit fraudsters is one thing, but actually giving bounty directly to criminals seems an altogether wilder crime-tackling tactic – though scheming Bangkok police recently faked a prize draw by sending out congratulatory letters informing over a dozen convicted criminals that their ID card numbers had been picked out of a hat and they'd won big, all in a sly attempt to draw the hard criminals in.

The cons, many of them months on the run and among them rapists and thieves, were pounced on when they turned up to collect the swag – TV sets and cash cheques being amongst the advertised prizes – and given rather less attractive jail sentences instead.
