(CBS/AP)-- Spanish authorities say they have arrested a Panamanian woman arriving at Barcelona airport with 1.38 kilograms of cocaine concealed in breast implants.

The Interior Ministry said Wednesday that border police noticed fresh scars and blood-stained gauze on her chest as well as pale patches beneath her skin.

The woman said she had recently had breast implant surgery. The statement said police were suspicious and sent her to a local hospital where the implants were removed and found to contain cocaine.

The woman arrived in Spain from Bogota, Colombia.

European authorities routinely submit passengers arriving from Latin America to stringent checks to combat drug smuggling.
