More than four kilos of cocaine, concealed in children’s books destined for Portugal, were confiscated by the Federal Police at Guarulhos airport, in São Paulo, from a South African citizen who was about to embark on a flight to Lisbon.

The 24-year-old woman was approached by police in the passenger queue at the flight check-in bound for Lisbon and during the interview, the passenger raised suspicions and the agents finally searched the luggage.

Inside the suitcase were found 10 children’s books and 48 small metal tubes packed similarly to capacitors. As the book covers appeared to be very thick, one of the covers was pierced, pouring a white substance.

Federal experts conducted tests and confirmed that the substances found inside the books and inside the tubes corresponded to more than four kilos of cocaine.
