In the wake of the deadliest terrorist attack in Iraq since 2003, Iraq’s prime minister Haider al-Abadi has instructed all the country’s security forces – the federal and local police and the army — to stop using fake bomb detectors at the hundreds of security checkpoints across the country.

The Independent reports that al-Abadi also ordered an investigation at the Ministry of the Interior into “corrupt deals” to buy the fake bomb detectors, known as ADE 651.

According to Homeland Defense News Wire, a British businessman, James McCormick, purchased thousands of the novelty golf ball finders for $19.95 each, repackaged them, and then sold them to Iraq and other nations as advanced hand-held bomb detectors. McCormick charged $40,000 for each of the repackaged golf-ball finders .

In 2013 McCormick was sentenced to ten years in jail for endangering lives for “obscene profits,” and ordered to pay millions in restitution. In all, McCormick, a former policeman, made $75 million from the Iraqi government alone. Iraq bought nearly 2,000 of the golf-ball finders and distributed them to hundreds of security checkpoints.

Despite vociferous U.S. objections, the Iraqi government of Nuri al-Maliki used millions of dollars in U.S. military aid to purchase thousands of the fake bomb-detectors.

The Iraqi government and Iraq’s security services refused to be persuaded by scientific analysis and demonstrations which proved the “detectors” to be a hoax.

Al-Abadi has now ordered the replacement of the fake detectors with X-ray systems, which will be installed at entry points into Baghdad.

The Iraqi government has also asked the United States for surveillance drones, which will scan an upgraded security belt around the Iraqi capital.
