Were fake bomb detectors used by hotel security in Sharm el-Sheikh?
Asked about images of the devices in use in the Red Sea resort where Flight 9268 began, a spokesman for the British Foreign Office said it had raised the issue with Egyptian authorities.
"We will continue to raise our concerns over the use of the devices in question," said the spokesman.
`Magic wand` detectors
The detectors -- consisting of a plastic case with a protruding antenna -- closely resemble the infamous ADE 651, a fake bomb detector sold throughout the Middle East and other hotspots by a British con man.
James McCormick was sentenced to 10 years in prison for fraud by a London court in 2013 over the scam, which netted him tens of millions of dollars in sales around the world and funded a luxurious lifestyle.
The device, which contained no working electronic components, was really a novelty golf ball finder with the label removed, British police said.
"These devices contain absolutely nothing inside. There`s no laws of science or physics that could make them work," Detective Inspector Edward Heath told CNN in 2013.
