A Panamanian women 28 years of age at the time of arrival at the airport of El Prat de Barcelona aroused the suspicions of border agents after answering some routine questions irregularly. The officers then conducted a body search, during which observed bloody bandages and recent scars on the breast of the woman.

Trasaladó it immediately to a hospital, where they found two plastic bags containing a total of 1.38 kilograms of cocaine, which had been surgically inserted under each breast. The arrest and subsequent operation may have saved the life of the young woman: "She was in bad shape when he arrived," police said. "She said it did not hurt anything, but the wounds were bad."

Surprisingly, this is not the first time that drug traffickers use surgery to avoid the police. Last year, a model in Rome Fiumicino Airport was caught with breast implants and buttocks containing 2.5 kg of cocaine. In 2006, authorities arrested 22 Colombians in the United States for heroin trafficking, who had surgically implanted under the skin of Labrador puppies.

These techniques are so drastic high risk smuggling, drug carriers - called "mules" - often pay a heavy price. In New Zealand, a woman died last year, when one of the 26 bags of cocaine he had swallowed burst inside her, releasing about 20 grams of the drug in your gut.

In 2007, a 23-year-old died on a transatlantic flight when several bags of cocaine were broken when he had swallowed. Mules often swallow the drugs after being placed inside of latex gloves or condoms, the drug is evacuated after arrival in the destination country, often by using laxatives.

The drug imaginations seem limitless. Other notable drug smuggling operations have hidden drugs within melons emptied inside spare tires, inside a ceramic tableware, swallowed by snakes and mixed with gypsum plaster used for a foot fracture.
