Dutch customs police turned a fake break into a real bust Friday when they stopped a woman trying to smuggle 3.3 pounds of cocaine into the country in a plaster cast on her leg.

Police spokesman Rob Stenacker said the woman, whose name was not released, acted nervously while her passport was being checked, and agents became suspicious about the thickness of the cast.

"She had two different letters from a doctor about her leg, and both of them appeared fake," Stenacker said. A sniffer dog quickly indicated that the cast contained more than plaster.

The woman was taken to hospital, where an X-ray revealed the drugs but no fractures.

Stenacker said the woman, from Suriname, was arrested and will face smuggling charges.
