A 25-year-old woman flying in from Rio de Janeiro in Brazil via Rome was arrested on Tuesday at Athens International Airport for attempting to smuggle more than 6 kilos of cocaine hidden in a parachute in her luggage.
Police said they were investigating whether the woman, a foreign national, was part of a wider network smuggling drugs into Greece from Latin America.
She was to appear before a prosecutor on Tuesday.
In a separate incident, a 51-year-old foreign national was arrested in Kozani, northern Greece, after police found more than 58 kilograms of cannabis in his car.
Police also arrested a 29-year-old passenger, an illegal migrant who was carrying a forged passport.
