Rivera department police seized more than 1,500 kilograms of marijuana, the largest such seizure in Uruguay’s history, the Interior Ministry announced in late November 2021.[1] The seizure came under Operation Ryguasu: after an investigation running since late September, when about 50 kilograms were seized and a man arrested, police tracked Paraguayan marijuana entering over land from Brazil and intercepted three vehicles carrying it in mid-November.[1] Officers stopped one vehicle with nearly 800 kilograms while the other two fled; a pickup truck hit a tree and rolled over, yielding more than 450 kilograms, and the abandoned third vehicle held nearly 330 kilograms.[1] Interior Minister Luis Heber and Attorney General Juan Gómez presented the result at a press conference as the largest marijuana seizure in the country’s history.[1]
