PARIS - Police at Paris' top airport lost track of a passenger's bag
in which plastic explosives were placed to train bomb-sniffing dogs,
police said Saturday....

French police said the explosives were harmless and there was no
chance of their going off, since no detonators were connected to them.

....

French police at Charles de Gaulle deliberately placed up to five
ounces of plastic explosives into a passenger's luggage Friday
evening, police spokesman Pierre Bouquin said.

But a "momentary lack of surveillance" led to the bag being lost on a
conveyor belt carrying luggage from check-in to planes, he said.

....

"Indeed, it's possible that someone will have a surprise when he opens
his bag."

One would hope that they left their Police Dept address in there
too?...likely "Keystone Kop Dept, Paris, France.
