British police have arrested the director of a company that sold a bomb detecting device to 20 countries.
Jim McCormick was arrested on suspicion of fraud after a BBC investigation found the ADE-651 bomb detector did not work.
The British government has announced a ban on the export of the device to Iraq and Afghanistan, where British forces are serving.
The biggest customer has been Iraq where the government has spent US$85m on the hand held wands which are being used at most checkpoints in Baghdad.
Jim McCormick claims that it works using special electronic cards slotted into it to detect explosives.
But the BBC had the card examined and it showed the card contained only a tag used by shops to prevent theft.
