Brazil’s Federal Police seized more than 12 tons of marijuana from a truck stopped late on Sunday 14 June 2009 at a checkpoint in Guaíra, in the southern state of Paraná near the Paraguayan border.[1] Officers called it the largest drug seizure in Brazil that year and one of the largest ever registered in the country.[1]

The marijuana was hidden in a timber shipment on a truck crossing near the Ayrton Senna Bridge, which links Paraná with Mato Grosso do Sul.[1] Officers decided to search the truck because the driver was nervous and kept contradicting himself.[1] The 50-year-old driver told police the load was bound for São Paulo.[1]
