A British millionaire has been found guilty of fraud, after making millions of pounds from selling fake bomb detectors.
James McCormick made around £50 million from selling the fake devices to countries like Iraq and Georgia.
The bogus kits created claimed to spot explosives. But they didn't work - and were actually based on a golf ball finder.
6000 were sold to Iraq where people thought they would help save lives.
Police say that some of the fake detectors are still being used at checkpoints in the Middle East.
Mr McCormick claimed the devices would work under water and would track an object up to 1000 metres below the ground.
But that was all a lie. In reality McCormick's device was based on £13 golf ball finders which he had bought from the US and which had no working electronics.
One senior Iraqi official told the BBC that the useless devices had created a false sense of security - and that no punishment would make up for the blood that had been shed as a result.
McCormick will be sentenced on 2 May.
